+
+CAS detectors distances modified
+
+The distances between the CAS detectors has been modified based on the
+latest CAD drawings. 
+
+2 November 2002, Bari
+
+CALORIMETER geometry upgrade
+
+The volumes CAPD and CAAD have been taken off from the calorimeter.
+In addition the logical tree has been slightly changed to make the shifts of
+the silicon planes into the calorimeter box easier, i.e. the CAPL volume,
+which was made of the CASI, CAKP, CAGL, C10C and CAKA volumes, has
+been split up in the volumes CANS and CAPL. Now CANS is made of the CAKP,
+CAGL, C10C and CAKA volumes while CAPL contains the CASI volume, that has to
+be shifted as a function of the vertical position in the calorimeter. Also the
+dimensions of some volumes have been upgraded, including the external ones:
+CALB and CALS. CALS is an aluminum box of dimensions: 48.4*48.4*21.278 cm^3,
+having side-walls 1 cm thick and a bottom of 1 mm. The real box is more
+complicated and the configuration of the bottom should be upgraded if we want
+a reliable description of the event in the S4 scintillator.

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