DellAcqua +DECK,zsctgeo,T=Geant. *CMZ : 24/08/95 00.16.12 by Pavel Nevski *-- Author : Steve Snow 18/10/95 **************************************************************** MODULE ZSCTGEO Geometry of the SCT forward tracker **************************************************************** Author Reinier D , Maya S , Steve S Created 18 Oct 1995 * * Modified 16 June 1997 J.Pater * - put the services through two trt gaps not one * * Modified 29 April 97 S.Snow * - changed ring 4 from GaAs to Si ( material type and thickness changed ) * * Modified September 1996 S.Snow: * - Changed AlArea to reflect latest estimate of power tapes from engineers. * - Changed silicon thickness to 300 microns to be consistent * with barrel ( was 280 microns ). * - Increase DqSub from 0.9 to 2.0 cm and DrCool from 1.2 to 2.0 cm * in rings 1 and 2 . This increases the radiation length of the * silicon module + support + services to the new round number * of 2.00 % exactly. * * Modified August 1996 S.Snow: Rationalised description of cooling * block to get rid of historical fudge-factors. * - Halved thickness and doubled density of ZELE so that the gap between two * sensitive volumes in a module is now a realisitc 340 microns ( was 640 ). * - Put in realistic values for DfWheel ( previously it was 0 ). * - Fixed a bug in wheel Z positions. They were offset by 0.5 cm from * intended positions due to a feature of the age language. * ( another feature I just discovered is that if you put the word feature * in inverted commas here it is no longer treated as part of the comment ) * - Reduced ZSCG_ZloEnd by 0.5cm to 81.5 ( checked that there is still * clearance between it and inafgeo ) * * Modified 17 May 1996 S.Snow: got rid of ZSCT volume, now position * the ZENDs directly in INNE * * Modified 8 May 1996 J.Pater: removed ZSBK and ZWRI from content * statement as they no longer exist * Modified 22 April 1996 J.Pater * - got rid of unused variables to stop compiler complaints * - fixed typo in z position of 9th wheel: was 278.8, should be 277.8 *--------------------------------------------------------------- +CDE,AGECOM,GCONST,GCKINE,GCUNIT Content ZISO,ZEND,ZINN,ZWEI,ZWSU,ZRII,ZMOD,ZDET,ZSEN,ZELE, ZSUB,ZOUT,ZOSF,ZOCP,ZOCA,ZBIP,ZALP Structure ZSCG { VERSION,NWHEEL,DZWHEEL,DZDISC,RINT,RINEND, ROUEND,ZLOEND,ZHIEND,THINSU,THSF, ZTRTGAP1,ZTRTGAP2,DZGAP,ALAREA,RBIP } Structure ZSCW { WHEEL,ZWHEEL,DFWHEEL,RIDISC,SGNSTO,NORING, LIRING(4),ZSRING(4)} Structure ZSCR { RING,MAT,NMODUL,DFMOD,RISI,ROSI,RIELE,ROELE,STEREO, DRCOOL,DQCOOL,DZCOOL,DQSUB,DZSC,DZSUB,DZELE,STAGGER } REAL ZCENTRE,ZHLEN,T2,TDET,RR,DR,RSTEP,ROSF,ROCP,AREA,UMODS,EAV, _ FIFI,FI,XX,YY,DDZZ,ZPOS,ZGAP,RING,RIN,ROUT,RITHI,DQele,DfDet,ZCEND,ZHEND INTEGER Iwheel,Iring,M,Istag,IRS,Mat Fill ZSCG !
