19 | TOF geometry description as installed (G. Cara Romeo, A. De Caro) | |
20 | ||
dfef1a15 | 21 | Revision 0.1 2007 March G. Cara Romeo and A. De Caro |
22 | Implemented a more realistic TOF geometry description, | |
23 | in terms of: | |
24 | - material badget, | |
25 | - services and front end electronics description, | |
26 | - TOF crate readout modules | |
27 | (added volume FTOS in ALIC_1/BBMO_1/BBCE_%i -for i=1,...,18-, | |
28 | and in ALIC_1/BFMO_%i -for i=19,...,36- volumes) | |
29 | As the 5th version in terms of geometrical positioning of volumes. | |
