18 | Revision 1.27 2001/04/06 11:24:43 morsch |
| 19 | Dependency on implementations of AliSegmentation and AliMUONResponse moved to AliMUONFactory class. |
| 20 | Static method Build() builds the MUON system out of chambers, segmentation and response. |
| 21 | |
| be3bb6c1 |
22 | Revision 1.26 2001/03/17 10:07:20 morsch |

25 | Revision 1.25 2001/03/16 15:32:06 morsch |
| 26 | Corrections of overlap with beam shield and dipole (A. de Falco) |
| 27 | |

38 | Revision 1.21 2000/12/20 13:00:22 egangler |
| 39 | |
| 40 | Added charge correlation between cathods. |
| 41 | In Config_slat.C, use |
| 42 | MUON->Chamber(chamber-1).SetChargeCorrel(0.11); to set the RMS of |
| 43 | q1/q2 to 11 % (number from Alberto) |
| 44 | This is stored in AliMUONChamber fChargeCorrel member. |
| 45 | At generation time, when a tracks enters the volume, |
| 46 | AliMUONv1::StepManager calls |
| 47 | AliMUONChamber::ChargeCorrelationInit() to set the current value of |
| 48 | fCurrentCorrel which is then used at Disintegration level to scale |
| 49 | appropriately the PadHit charges. |

85 | Revision 1.10 2000/10/12 16:07:04 gosset |
| 86 | StepManager: |

| 109 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) |
| 110 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON |
| 111 | framework. The changes should have no side effects (mostly dummy arguments). |
| 112 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation |
