19 | New files for folders and Stack | |
20 | ||
9e1a0ddb | 21 | Revision 1.27 2001/04/06 11:24:43 morsch |
22 | Dependency on implementations of AliSegmentation and AliMUONResponse moved to AliMUONFactory class. | |
23 | Static method Build() builds the MUON system out of chambers, segmentation and response. | |
24 | ||
be3bb6c1 | 25 | Revision 1.26 2001/03/17 10:07:20 morsch |
26 | Correct inconsistent variable name / method name / comments. | |
27 | ||
2eb55fab | 28 | Revision 1.25 2001/03/16 15:32:06 morsch |
29 | Corrections of overlap with beam shield and dipole (A. de Falco) | |
30 | ||
21a18f36 | 31 | Revision 1.24 2001/03/14 17:22:15 pcrochet |
32 | Geometry of the trigger chambers : a vertical gap of has been introduced around x=0 according fig.3.27 of the TDR (P.Dupieux) | |
33 | ||
236fe2c5 | 34 | Revision 1.23 2001/01/18 15:23:49 egangler |
35 | Bug correction in StepManager : | |

40 | ||
a7e8b51a | 41 | Revision 1.21 2000/12/20 13:00:22 egangler |
42 | ||
43 | Added charge correlation between cathods. | |
44 | In Config_slat.C, use | |
45 | MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of | |
46 | q1/q2 to 11 % (number from Alberto) | |
47 | This is stored in AliMUONChamber fChargeCorrel member. | |
48 | At generation time, when a tracks enters the volume, | |
49 | AliMUONv1::StepManager calls | |
50 | AliMUONChamber::ChargeCorrelationInit() to set the current value of | |
51 | fCurrentCorrel which is then used at Disintegration level to scale | |
52 | appropriately the PadHit charges. | |
53 | ||
681d067b | 54 | Revision 1.20 2000/12/04 17:48:23 gosset |

89 | StepManager: | |
90 | * SigGenCond only called for tracking chambers, | |
91 | hence no more division by 0, | |
92 | and may use last ALIROOT/dummies.C with exception handling; | |
93 | * "10" replaced by "AliMUONConstants::NTrackingCh()". | |
94 | ||

110 | ||
8c449e83 | 111 | Revision 1.5 2000/06/28 15:16:35 morsch |
112 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
113 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
114 | framework. The changes should have no side effects (mostly dummy arguments). | |
115 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
116 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
117 | ||
802a864d | 118 | Revision 1.4 2000/06/26 14:02:38 morsch |
