23 | ||
9e1a0ddb | 24 | Revision 1.27 2001/04/06 11:24:43 morsch |
25 | Dependency on implementations of AliSegmentation and AliMUONResponse moved to AliMUONFactory class. | |
26 | Static method Build() builds the MUON system out of chambers, segmentation and response. | |
27 | ||
be3bb6c1 | 28 | Revision 1.26 2001/03/17 10:07:20 morsch |
29 | Correct inconsistent variable name / method name / comments. | |
30 | ||
2eb55fab | 31 | Revision 1.25 2001/03/16 15:32:06 morsch |
32 | Corrections of overlap with beam shield and dipole (A. de Falco) | |
33 | ||
21a18f36 | 34 | Revision 1.24 2001/03/14 17:22:15 pcrochet |
35 | Geometry of the trigger chambers : a vertical gap of has been introduced around x=0 according fig.3.27 of the TDR (P.Dupieux) | |
36 | ||
236fe2c5 | 37 | Revision 1.23 2001/01/18 15:23:49 egangler |
38 | Bug correction in StepManager : | |

43 | ||
a7e8b51a | 44 | Revision 1.21 2000/12/20 13:00:22 egangler |
45 | ||
46 | Added charge correlation between cathods. | |
47 | In Config_slat.C, use | |
48 | MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of | |
49 | q1/q2 to 11 % (number from Alberto) | |
50 | This is stored in AliMUONChamber fChargeCorrel member. | |
51 | At generation time, when a tracks enters the volume, | |
52 | AliMUONv1::StepManager calls | |
53 | AliMUONChamber::ChargeCorrelationInit() to set the current value of | |
54 | fCurrentCorrel which is then used at Disintegration level to scale | |
55 | appropriately the PadHit charges. | |
56 | ||
681d067b | 57 | Revision 1.20 2000/12/04 17:48:23 gosset |

61 | * mean noise at 1.5 ADC channel | |
62 | * Ar-CO2 gas (80%+20%) | |

f9f7c205 | 91 | Revision 1.10 2000/10/12 16:07:04 gosset |
92 | StepManager: | |
93 | * SigGenCond only called for tracking chambers, | |
94 | hence no more division by 0, | |
95 | and may use last ALIROOT/dummies.C with exception handling; | |
96 | * "10" replaced by "AliMUONConstants::NTrackingCh()". | |
97 | ||

113 | ||
8c449e83 | 114 | Revision 1.5 2000/06/28 15:16:35 morsch |
115 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
116 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
117 | framework. The changes should have no side effects (mostly dummy arguments). | |
118 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
119 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
120 | ||
802a864d | 121 | Revision 1.4 2000/06/26 14:02:38 morsch |
