S4 GEOMETRY UPDATED: |
| 80 |
|
The x and y dimensions have been corrected because they were wrong. |
| 81 |
|
A container of aluminum has been added having walls of thickness equal |
| 82 |
|
to 0.1 cm. |
| 83 |
|
|
| 84 |
|
TOF POSITIONS DEFINITELY UPDATED: |
| 85 |
|
S2 and S1 have been positioned again, after the simulation of the top plate. |
| 86 |
|
Before now, the positions were put ad hoc based on the positions given by |
| 87 |
|
Sergio Ricciarini in the document 'Main geometrical parameters of the PAMELA |
| 88 |
|
sub-detectors' released by O. Adriani, L. Bonechi, E. Mocchiutti and |
| 89 |
|
S. Ricciarini on the 20th of December 2005.. These positions were |
| 90 |
|
lightly approximated. |
| 91 |
|
|
| 92 |
|
ND GEOMETRY COMPLETED. |
| 93 |
|
The He3 and the polyethylene (CH2) have been added to fill |
| 94 |
|
the volumes NDTI and NDPB in the neutron detector. Leonov gave us the |
| 95 |
|
details of these materials. |
| 96 |
|
|
| 97 |
|
TOP PLATE GEOMETRY ADDED. |
| 98 |
|
The top plate geometry has been simulated as a N2 box that has the same |
| 99 |
|
dimensions of CATA. Inside it, at the right positions, there are S2 and CATA. |
| 100 |
|
The real top plate is a rectangular window having a thickness of 0.5 cm |
| 101 |
|
(volume TPTL emptied by the volume TPCV). This volume is filled with a mixture |
| 102 |
|
of titanium (90%), aluminum (6%) and vanadium (4%). Other parts of titanium |
| 103 |
|
are the four volumes TPTU, which are positioned at the corners of TPTL at the |
| 104 |
|
same height of CATA, and the four volumes TPTM, which are positioned at the |
| 105 |
|
corners of TPTL, at the same height of S2. |
| 106 |
|
The geometry of the top plate is based on a simplified version of the CAD |
| 107 |
|
drawings. |
| 108 |
|
|
| 109 |
|
October 2006, Bari |
| 110 |
|
|
| 111 |
|
The geometry of the neutron detector has been updated. Some dimensions of some |
| 112 |
|
volumes have been corrected and the aluminum cover and the aluminum boxes to |
| 113 |
|
put the cables have been added. A new material, the cadmium, has been also |
| 114 |
|
defined. |
| 115 |
|
|
| 116 |
|
September 2006, Bari |
| 117 |
|
|
| 118 |
|
SPHE and ND data card bugs fixed: the definition of the ND data card, |
| 119 |
|
missing in the subroutine gpgeo.F, has been added; the meaning of the SPHE |
| 120 |
|
data card has been changed. Before the correction the data card: |
| 121 |
|
NDET 'SPHE' was used to delete the spherical top shell to substitute it with |
| 122 |
|
a flat one.Now NDET 'SPHE' eliminates the whole container of PAMELA. |
| 123 |
|
|
| 124 |

|
|
| 127 |
|
The center of the scintillator planes S22Y (variable ZPAMS22Y in gpdgeo.inc) |
| 128 |
|
and S12X (variable ZPAMS12X in gpdgeo.inc) has been positioned at the |
| 129 |
|
nominal height as measured in PAMELA (See the document: "Main geometrical |
| 130 |
|
parameters of the PAMELA sub-detectors" by O. Adriani, L. Bonechi, |
| 131 |
|
E. Mocchiutti, S. Ricciarini, 20 December 2005). Follows that the positions |
| 132 |
|
of S21Y and S12X are higher than those in the cited document due to the fact |
| 133 |
|
that in GPAMELA the thickness of the mylar has been considered while in the |
| 134 |
|
document it has been neglected. |

GIGANTIC RESONANCE FOR NEUTRON DETECTOR ADDED |
| 140 |
|
|
| 141 |
|
Routines to simulate the gigantic resonance of gammas in Tungsten |
| 142 |
|
have been added. The GPGIG routine is called in GUSTEP if a gamma |
| 143 |
|
enter the calorimeter absorber. This is the steering routine to |
| 144 |
|
simulate the production of neutrons from gigantic resonance. It |
| 145 |
|
does checks on STEP lenght. If the range is smaller than the other |
| 146 |
|
selected for that step, it does generate the neutron and stops the |
| 147 |
|
gamma. Please note that the neutron has now a new particle |
| 148 |
|
number. This is to tag the gigantic resonance neutrons. |

CAL HIT STRUCTURE BUGS FIXED |
| 154 |
|
|
| 155 |
|
The maximum number of hit is now different for the two hit |
| 156 |
|
structures: CALST and CALI. Vectors inizialization and HBOOK |
| 157 |
|
ntple booking have been updated. The GPDCAL routine has been fixed |
| 158 |
|
so to handle the case in wich hits stored are more than the maximum |
| 159 |
|
number of hit. |
| 160 |
|
In this case in the ntple up to the maximum number of hits will be stored. |

TOF GEOMETRY AND POSITIONS UPDATED AND NEW MIXTURES ADDED |
| 165 |
|
|
| 166 |
|
The TOF geometry has been modified. The following boxes have been |
| 167 |
|
added: POL1, POL2 and POLY made of polystyrene, S11M, S12M, S21M, |
| 168 |
|
S22M, S31M and S32M made of mylar, S1A, S2A and S3 made of air and |
| 169 |
|
S1 and S2 made of aluminum. Each scintillator paddle has been put |
| 170 |
|
in his mylar box and the other materials: air, polystyrene, and |
| 171 |
|
aluminum have been added at their nominal positions. According to |
| 172 |
|
Naples people the araldite glue has been simulated has an air |
| 173 |
|
gap. For this work two new materials: the Mylar (MYLAR) and the |
| 174 |
|
polystyrene (POLYSTYRENE) with a density of 35 g/l have been |
| 175 |
|
defined as a mixture. The positions of the three bottom |
| 176 |
|
scintillator planes that contain respectively the S12X, S22Y and |
| 177 |
|
S32X paddles have been regulated according on their official |
| 178 |
|
positions in PAMELA. |

GEN DATA CARD UPDATED |
| 183 |
|
|
| 184 |
|
To enable generation on a surface perpendicular to the XY plane, |
| 185 |
|
GEN gata card has been updated addingh a new parameter: ZDGEN. This is |
| 186 |
|
the dimension, along Z axis , of the generation surface. The Z |
| 187 |
|
position will be randomply chosen according to: Z= ZDGEN*RNDM_NUMBER + |
| 188 |
|
ZGEN, i.e. Z= GEN(6)*RNDM_NOMBER + GEN(3). |

|
GUHADR AND GUPHAD UPDATED |
| 193 |
|
|
| 194 |
|
To use GCALOR package the hadronic routines have been updated. The |
| 195 |
|
inizialization routine call CALSIG, while the other calls GCALOR. |
| 196 |
|
|
| 197 |
|
NEW GPKEY ADDED: GPCALOR |
| 198 |
|
|
| 199 |
|
This logical has been added to enable the GCALOR package. This flag |
| 200 |
|
is set to true in GPDAT if the data card: HPAK, is set to |
| 201 |
|
'GCAL'. The gpkey.inc has been update accordingly. |
| 202 |
|
|
| 203 |
|
|
| 204 |
|
NEUTRON DETECTOR ADDED. NEW DIR: GPND |
| 205 |
|
|
| 206 |
|
The neutron detector has been added. At the moment it is just the |
| 207 |
|
geometry. The directory structure of the repository has been |
| 208 |
|
updated as well. Dimensions has been taken from picture and |
| 209 |
|
literature. A full upgrade to the drawing is needed. |
| 210 |
|
|
| 211 |
|
GCALOR PACKAGE ADDED. NEW DIRs: GPCALOR, GPCALORDES |
| 212 |
|
|
| 213 |
|
GCALOR package contins the CALOR simulation code and an interface |
| 214 |
|
to use it in GEANT. The important feature for us is the usage of |
| 215 |
|
the MICAP code. This is facused on the low energy neutron |
| 216 |
|
simulation. for details see: |
| 217 |
|
http://www.staff.uni-mainz.de/zeitnitz/Gcalor/gcalor.html |
| 218 |
|
This package should be distributed with the GEANT library but is |
| 219 |
|
not up to date. I did download the latest release and stored into |
| 220 |
|
gpcalor directory of the gpamela tree. |
| 221 |
|
Then I did clean up the code substituting the explicit inclusion of |
| 222 |
|
the commons with a #include cpp directive. In parallel I did |
| 223 |
|
extract the commons to include files having the same common name. I |
| 224 |
|
did store the include files into a newly created directory: |
| 225 |
|
gpcalordes. |
| 226 |
|
The Makefile has been updated accordingly. |
| 227 |
|
Please note that to avoid conflict with CRENLIB distribution the gcalor source file has been named gpcalor.F |
| 228 |
|
NOTE: There are still problem due to different common sizes. In |
| 229 |
|
particular the common MICFIL is maller in the geant library |
| 230 |
|
libgeant.a . There the subroutines: gmorin, gmxsec, gmplxs, are |
| 231 |
|
present and linked using a wrong version of the common. This still needs to be debuged. |
| 232 |
|
NOTE2: The auxiliary files with the cross sections: chetc.dat.gz |
| 233 |
|
and xsneut.dat.gz, have been added to the aux directory and moved |
| 234 |
|
to the working directory, i.e. GPAMELA_BIN. The GCALOR routine will |
| 235 |
|
look for CERN_ROOT environment variable. If found files are |
| 236 |
|
searched there at first, then in the working directory. A fool |
| 237 |
|
proof policy has to be implemented to avoid problem with |
| 238 |
|
synchronization fo these files. |

TOF SCINTILLATOR PADDLES UPDATED |
| 246 |
|
|
| 247 |
|
The dimensions and the number of the scintillator paddles for each |
| 248 |
|
TOF planes have been updated. |
| 249 |
|
|
| 250 |
|
May 2005, Bari |
| 251 |
|
|
| 252 |
|
Some updates on the latest modification done in the past year. |
| 253 |
|
|
| 254 |
|
NEW DATA CARD ADDED: HFSF |
| 255 |
|
|
| 256 |
|
To define a policy for the random number initial seeds |
| 257 |
|
definition. Using this card is possible to override GEANT seeds |
| 258 |
|
defined via NRDM card. The policy is selected according to the |
| 259 |
|
values: |
| 260 |
|
|
| 261 |
|
- 1: The seeds are initialized to the initial values found in a user |
| 262 |
|
defined file or the default file: INPUTSEED.DAT |
| 263 |
|
|
| 264 |
|
- 2: The seeds are initialized to the final values found in a user defined |
| 265 |
|
file or the default file: INPUTSEED.DAT |
| 266 |
|
|
| 267 |
|
The case 1 must be used in case the user needs to reproduce the |
| 268 |
|
random chain of a previous run. In this case the user can save the |
| 269 |
|
initial seeds, used in the run he would like to reproduce, in a |
| 270 |
|
binary file and pass the filename to the program using the *FLSF |
| 271 |
|
data card. In case the user file is not specified the default |
| 272 |
|
INPUTSEED.DAT will be used. |
| 273 |
|
|
| 274 |
|
The case 2 must be used in case the user needs to chain several |
| 275 |
|
GPAMELA run and likes to be sure he is starting the random |
| 276 |
|
generator using the right sequence. In this case the user must |
| 277 |
|
specify an input binary file using the *FLSF data card, otherwise |
| 278 |
|
the INPUTSEED.DAT file will be used. |
| 279 |
|
|
| 280 |
|
NEW DATA CARD ADDED: *FSFI |
| 281 |
|
|
| 282 |
|
Using this card the user can specify the logical unit and name of |
| 283 |
|
the file storing the initial seeds to be used to initialize the |
| 284 |
|
random number generator. This file must be a FORTRAN binary one |
| 285 |
|
storing four integer numbers. The first two are the number to be |
| 286 |
|
used in the case: HFSF=1, the other two will be used in the case: |
| 287 |
|
HFSF=2. This file can be one created by GPAMELA or by the user |
| 288 |
|
filled with his own seeds. For this purpose an utility program: |
| 289 |
|
writeseeds.f, has been added in the aux directory. In case the |
| 290 |
|
*FSFI card is not specified the default values: 24 and INPUTSEEDS.DAT, will |
| 291 |
|
be used as LUN and file name respectively. |
| 292 |
|
|
| 293 |
|
NEW DATA CARD ADDED: *LSFI |
| 294 |
|
|
| 295 |
|
Using this card the user can specify the logical unit and name of |
| 296 |
|
the file storing the first and last seeds used in the GPAMELA |
| 297 |
|
run. This file is a FORTRAN binary one. This file can be used as |
| 298 |
|
input one specifying it in the *FSFI data card of the next GPAMELA |
| 299 |
|
run. In case the *LSFI card is not specified the default values: 26 |
| 300 |
|
and HBOOKFILENAME.DAT (as sepified in *HFI), will be used as LUN |
| 301 |
|
and file name respectively. |
| 302 |
|
|
| 303 |
|
NEW UTILITY PROGRAMS ADDED: writeseeds.f, readseeds.f |
| 304 |
|
|
| 305 |
|
These new programs have been added in the aux directory. Using these a |
| 306 |
|
user defined seed file can be created and re-read. |
| 307 |
|
|
| 308 |
|
NEW VOLUMES ADDED: MSHE, BSPH; PRESSURIZED CONTAINER ADDED |
| 309 |
|
|
| 310 |
|
Alexey Bakaldin, in MEPHI, did add the PAMELA pressurized container to |
| 311 |
|
the simulation. He did defined new volumes filled with aluminum and |
| 312 |
|
placed inside the mother volume. Positions have been fine tuned by |
| 313 |
|
Marialuigia Ambriola and compared to the CAD drawings. |
| 314 |
|
Two new volumes have been added to simulate the container: |
| 315 |
|
- MSHE, a tube simulating the middle part of the container |
| 316 |
|
- BSPH, the spherical bottom part of the container |
| 317 |
|
|
| 318 |
|
To better simulate the upper part the SHEL volume has been modified |
| 319 |
|
into a cone. Dimentions of the top cover: TSPH, have been modified |
| 320 |
|
accordingly. |
| 321 |
|
|
| 322 |
|
DETECTOR POSITIONS REVIEWED |
| 323 |
|
|
| 324 |
|
All detector Z positions have been reviewd to fit into the |
| 325 |
|
simulated pressurized container. |
| 326 |
|
|
| 327 |
|
TRD GEOMETRY AND CALIBRATION REVIEWD |
| 328 |
|
|
| 329 |
|
The TRD geometry has been deeply reviewed. Using the CAD drawings |
| 330 |
|
the carbon fiber frames have been simulated and radiator dimentions |
| 331 |
|
corrected. For this reason the calibration done on the beam tests |
| 332 |
|
has been revied and new sets of calibration constants calculated |
| 333 |
|
comparing the beam test data with the GPAMELA results. The new |

TRACKER GEOMETRY REVIEWED. NEW VOLUME DEFINED: THBP, TPAS, TPAI |
| 337 |
|
|
| 338 |
|
Thanks to Lorenzo Bonechi for the drawings and explanations. Now the |
| 339 |
|
hybrd cards have been put into the simulation and the geometry updated |
| 340 |
|
considering the dead zones in the silicon detectors. The hybrid zone |
| 341 |
|
has been simulated as well. At the moment the hybrid is simulated as |
| 342 |
|
a G10 plates. The full height of the tracker magnet has been |
| 343 |
|
reviewed as well. |
| 344 |
|
|
| 345 |
|
The tracker ladder is now simulated inside a nitrogen box: TPAS, |
| 346 |
|
placed inside an aluminum frame: TRPB. Each silicon ladder has been |
| 347 |
|
simulated using two silicon blocks: TRSL, into each of this block a |
| 348 |
|
smaller silicon detector: TPAI, has been placed inside the larger |
| 349 |
|
silicon block TRSL. In this way the subdivided silicon ladder can |
| 350 |
|
be upgraded with an indipendend roto-translation for each sensor. |
| 351 |
|
|
| 352 |
|
The TRPB aluminum frame has been enlarged to fit the external |
| 353 |
|
magnet canister frame. |
| 354 |
|
|
| 355 |
|
The last plane has been flipped with a 180 degree rotation around |
| 356 |
|
the X axis. |

NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED. |
| 371 |
|
The non-reproducibility of a GPAMELA run was due to the random number |
| 372 |
|
initialization in the GARFIELD code. In GARFIELD by default, the initial |
| 373 |
|
seeds of the random number generators are always the same while the random |
| 374 |
|
number generators are called a given number of times (determined by the |
| 375 |
|
hour of the day) during the initialization phase (see init.f subroutine in |
| 376 |
|
the GARFIELD code for details). Follows that different runs produce |
| 377 |
|
different results without changing the initial seeds. To have identical |
| 378 |
|
results in different runs, the GARFIELD program has to start typing the |
| 379 |
|
noRNDM_initialisation switch. To avoid of specifying this switch |
| 380 |
|
by the user, |
| 381 |
|
the GARFIELD package has been upgraded with a patch. In this way the problem |
| 382 |
|
is partially solved because, now, the initial seeds of the random generators |
| 383 |
|
in GARFIELD will be always the same even if the RNDM GEANT data card is |
| 384 |
|
activated by the user for changing the initial seeds in the GPAMELA program. |
| 385 |
|
Work is in progress for a more general correction of this problem. |
| 386 |
|
Please, use the updated GARFIELD code released with the CVS version v4r1 |
| 387 |
|
to fix this problem. |

RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS. |
| 391 |
|
The obsolete RNDM random number generator has been replaced by the GEANT |
| 392 |
|
GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function. |
| 393 |
|
|
| 394 |
|
BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL |
| 395 |
|
and IDCASI variables) used in GUTREV were respectively set to a fixed |
| 396 |
|
values of 12 and 1. The correct values of these variables are stored in |
| 397 |
|
the GPSED common when the set and the detector ZEBRA banks are filled |
| 398 |
|
during a run. In general the values of the set and detector addresses |
| 399 |
|
depend on the number of active detectors in a given run. ISCAL=12 and |
| 400 |
|
IDCASI=1 are only right when all the detectors of GPAMELA are active. |
