Revision 1.12 2001/03/16 16:26:05 morsch
Put vacuum in beam-pipe not air.
Revision 1.11 2000/10/27 15:21:24 morsch
Shield composition after muon project leader meeting: 24/10/2000
- 1 cm recess in steel for station 3
- no heavy shielding between chambers for stations 1 and 2
Revision 1.10 2000/10/02 21:28:15 fca
Removal of useless dependecies via forward declarations
Revision 1.9 2000/09/12 17:00:45 morsch
Overlaps in YMO3 and YMO4 (side-effect from last update only) corrected.
Revision 1.8 2000/09/12 16:11:43 morsch
- Bug in volume YGO2 corrected: PCON started with twice the same z-value.
- Recesses for chambers added to outer Pb cone.
Revision 1.7 2000/06/15 09:40:31 morsch
Obsolete typedef keyword removed
Revision 1.6 2000/06/13 15:01:38 morsch
Make kind of heavy shielding material (Pb, NiCuW) dependent on presence of outer cone.
Revision 1.5 2000/06/12 19:40:00 morsch
New structure of beam pipe and heating jacket.
Optional outer Pb cone added. Not yet compatible with chamber inner radii.
Revision 1.4 2000/04/03 08:13:40 fca
Introduce extra scope for non ANSI compliant C++ compilers
Revision 1.3 2000/01/17 10:29:30 morsch
Overlap between Shield and Absorber due to limited numerical precision removed
by displacing the Shield by epsilon = 0.01 cm.
Revision 1.2 2000/01/13 11:27:51 morsch
Overlaps corrected: YCS3, YCS4; Inner radius YS21 corrected
Revision 1.1 2000/01/12 15:44:03 morsch
