Abstract

Author Pavel Nevski

Created March 16, 1996

*  Original Version - Peter Jacobs (LBL), March 16, 1995.                   *
*  dimensions checked with the latest design with D.Fritz and H.Weiman      *
*  modification history                                                     *
*  PN  04/04/96: MWC sensitive volumes added into TPC sectors               *
*  WJL 04/15/97: changed no of pads in rows 10, 13, and 38                  *
*  WJL 05/07/97: changed divisioning of TMSE to work with new /sim/mws      *
*  PN  05/29/97: interpolation inside padrow corrected                      *
*                Laser hits generated in a special subroutine TPCELASER     *
*  PN  06/28/97: gas in pseudo-padrows and MWC volumes corrected            *
