24    CAS detectors distances modified
25    
26    The distances between the CAS detectors has been modified based on the
27    latest CAD drawings.

31    CALORIMETER geometry upgrade
32    
33    The volumes CAPD and CAAD have been taken off from the calorimeter.
34    In addition the logical tree has been slightly changed to make the shifts of
35    the silicon planes into the calorimeter box easier, i.e. the CAPL volume,
36    which was made of the CASI, CAKP, CAGL, C10C and CAKA volumes, has
37    been split up in the volumes CANS and CAPL. Now CANS is made of the CAKP,
38    CAGL, C10C and CAKA volumes while CAPL contains the CASI volume, that has to
39    be shifted as a function of the vertical position in the calorimeter. Also the
40    dimensions of some volumes have been upgraded, including the external ones:
41    CALB and CALS. CALS is an aluminum box of dimensions: 48.4*48.4*21.278 cm^3,
42    having side-walls 1 cm thick and a bottom of 1 mm. The real box is more
43    complicated and the configuration of the bottom should be upgraded if we want
44    a reliable description of the event in the S4 scintillator.

48    ANTICOINC. GEOMETRY UPGRADE
49    
50       The AC geometry has been updated. The top AC scintillator (CAT) now
51       consists of 1 single sheet of scintillator with a hole in the middle
52       and the correct geometry(*). The side AC scintillators (CAS) also
53       have the correct shape. The AC scintillators are placed in aluminum
54       boxes with plastic rims inside. For these rims a 'new' material, PLAS,
55       was defined. PLAS has all the characteristics of SCIN but is
56       non-sensitive. No PMTs or PMT holders have been modelled.
57       (*)-The interfaces on CAT where the PMTs should be located are
58           slightly different from the real case.
