-Revision 1.15 2001/05/02 11:50:18 morsch
-New layout of the non-absorber side provided by Y. Viyogi. Not the final design
-but the prsent most realistic.
-
-Revision 1.14 2001/01/20 16:56:33 morsch
-Put air in connecting tubes and flanges of vacuum pump.
-
-Revision 1.13 2001/01/20 16:35:27 morsch
-Increase mother volume for bellows.
-
-Revision 1.12 2000/12/21 16:41:06 morsch
-Coding convention clean-up (RS3)
-
-Revision 1.11 2000/11/28 16:06:57 morsch
-Undulated beam-pipe replaced by Al-Be (40,60) pipe 1.5 mm thick.
-
-Revision 1.10 2000/11/24 13:00:37 morsch
-- Geometry and materials imported from euclid output
-- include comments
-- better struturing of volume tree
-- improved version of flange close to front absorber
-- more realistic pump materials
-- undulated beam pipe imported from v3.
