42 | Revision 1.29 2001/06/21 14:54:37 morsch | |
43 | Put volumes of station 3 into DIPO if present. (A. de Falco) | |
44 | ||
45 | Revision 1.28 2001/05/16 14:57:17 alibrary | |
46 | New files for folders and Stack | |
47 | ||
48 | Revision 1.27 2001/04/06 11:24:43 morsch | |
49 | Dependency on implementations of AliSegmentation and AliMUONResponse moved to AliMUONFactory class. | |
50 | Static method Build() builds the MUON system out of chambers, segmentation and response. | |
51 | ||
52 | Revision 1.26 2001/03/17 10:07:20 morsch | |
53 | Correct inconsistent variable name / method name / comments. | |
54 | ||
55 | Revision 1.25 2001/03/16 15:32:06 morsch | |
56 | Corrections of overlap with beam shield and dipole (A. de Falco) | |
57 | ||
58 | Revision 1.24 2001/03/14 17:22:15 pcrochet | |
59 | Geometry of the trigger chambers : a vertical gap of has been introduced around x=0 according fig.3.27 of the TDR (P.Dupieux) | |
60 | ||
61 | Revision 1.23 2001/01/18 15:23:49 egangler | |
62 | Bug correction in StepManager : | |
63 | Now the systematic offset with angle is cured | |
64 | ||
65 | Revision 1.22 2001/01/17 21:01:21 hristov | |
66 | Unused variable removed | |
67 | ||
68 | Revision 1.21 2000/12/20 13:00:22 egangler | |
69 | ||
70 | Added charge correlation between cathods. | |
71 | In Config_slat.C, use | |
72 | MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of | |
73 | q1/q2 to 11 % (number from Alberto) | |
74 | This is stored in AliMUONChamber fChargeCorrel member. | |
75 | At generation time, when a tracks enters the volume, | |
76 | AliMUONv1::StepManager calls | |
77 | AliMUONChamber::ChargeCorrelationInit() to set the current value of | |
78 | fCurrentCorrel which is then used at Disintegration level to scale | |
79 | appropriately the PadHit charges. | |
80 | ||
81 | Revision 1.20 2000/12/04 17:48:23 gosset | |
82 | Modifications for stations 1 et 2 mainly: | |
83 | * station 1 with 4 mm gas gap and smaller cathode segmentation... | |
84 | * stations 1 and 2 with "grey" frame crosses | |

118 | hence no more division by 0, | |
119 | and may use last ALIROOT/dummies.C with exception handling; | |
120 | * "10" replaced by "AliMUONConstants::NTrackingCh()". | |

137 | ||
138 | Revision 1.5 2000/06/28 15:16:35 morsch | |
139 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
140 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
141 | framework. The changes should have no side effects (mostly dummy arguments). | |
142 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
143 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
