Discussion on Combined (ID+LAr) Material Studies action plan  Latest LAr linearity plot from period 5  Discussion on test MC run production

14-Mar-06Discussion on combined (ID+LAr) Material Studies2Summary  Main issue: question on the need of extra material in front of the cryostat (about 0.15X0s)  During last LAr week the effect of a number of systematics on the layer response was discussed: some of them cause shifts to S1/S2 similar to the way extra material does However, extra material produces tails + may have different E-dependence  After the LAr week calculations done by Martin and G.Unal show significant change of the layer dimensions at cold (in our Sim we have the measured lengths). The change impacts the S1/S2 the same way extra material would  Necessary to rerun with a new geometry  Another point: new G4 v4.8 will soon be part of the Atlas releases. This has significant impact on the PS response but smaller impact on S1/S2. The accordion SF is larger.

14-Mar-06Discussion on combined (ID+LAr) Material Studies3 Linearity (just an example, periods 5+6) For details on what has happened in 2005: see Walter Lampl’s thesis My latest check-plot following the MC vs Data comparison presented in Feb LAr week, agrees with Walter’s conclusions. Calibration is fully based on MC (calibration hits) Data MC 9GeV MC: charge collection corrections vs phi not fully studied

14-Mar-06Discussion on combined (ID+LAr) Material Studies4 New effort  Form a group of people from both LAr and ID groups to collectively address the MC description: Effects of far upstream material (about 0.13X0, mostly air) Effects of extra material inside the ID MC description of the LAr Geant4 validation  Define a number of runs to be simulated and used for comparisons.  Discuss analyses sensitive to particular effects Example: number of tracks or hits in the ID vs upstream material Non-gaussian tails in the LAr etc

14-Mar-06Discussion on combined (ID+LAr) Material Studies5 Future: proposed runs (T.Atkinson + all)  9GeV (e/pi composite beam) 2107 (no extra ID material) 2150 (with extra ID material)  20GeV (electrons) 2413 (no extra ID material) 2295 (with extra ID material) 2300 (with extra ID material) NO FIELD 2397 (no extra ID material) NO FIELD  180GeV (electrons) 2463 (no extra ID material) Reference + top priority 2195 (with extra ID material) 2182 (with extra ID material) NO FIELD 2461 (no extra ID material) NO FIELD Reference + top priority

14-Mar-06Discussion on combined (ID+LAr) Material Studies6 Offline Releases  Our best bet: to be built this Thursday Has new LAr geometry (contraction in cold) Has “old” Geant4 sim v4.7 Disadvantage: MCS treated better in the new v4.8 Advantage: allows LAr to check the transition to the new geometry using the same G4 version (v4.7).  Rerun with a latest version which will have G4 v4.8 Is this ?
