9 Feb, MEG Software Status -for the coming review committee- Question from A.Blondel Our answer Schedule and Man power MEG Software Group

9 Feb, Question from A.Blondel Give a common goal to be achieved by the next review; “I have appreciated the presentation of the offline software team, with a team leader etc... As promised I come forth with the question: could you give us -- and yourself -- a common goal to be achieved with that software in time for the next review?”

9 Feb, The Answer MC unified framework –With double option: Tokyo or Pisa –Test on reduced number of PMTs Large Prototype MC unification –CEX beam test –Same offline package for DATA & MC Event Display –Initially GEANT3

9 Feb, MC Framework - the MC unified framework (with the double option: Tokyo or Pisa) of the final detector should be ready (or almost ready) for the next meeting at PSI; therefore, the test on reduced number of PMTs could be done in the separate programs and in the unified framework as check;

9 Feb, MC Framework for MEG(1) Unified framework with double option: –Tokyo or Pisa code, Framework based on: –Fortran 77, –CERNLIB, –ZEBRA, –GEANT3, Distributed via CVS.

9 Feb, MC Framework for MEG(2) Tree structure & skeleton … ready; Materials & tracking medium … merged; Event generator … stand alone & built-in; DC, TC, Magnet and B field … merged; ZEBRA structure … in progress; Scintillation photon tracking … in progress.

9 Feb, To be done: MEG MC Merge Liq. Xe Geometry; Test w/ reduced number of PMT in Liq. Xe; Digitization for all the sub detectors; Full reconstruction program; Offline database… ODB? Separate database (e.g.PostgreSQL, MySQL, etc.)?

9 Feb, Lproto CEX beam test - the same work will be done for the Large Prototype MC, probably in time for the October beam test; the Large Prototype data and MC will be analyzed with the same offline package;

9 Feb, LProto CEX beam test MC merge into the new framework … just finished. –Common output format for DATA/MC; –Scintillation photon tracking in Liq. Xe … Full ray tracing or geometrical tracking; –Reflection on the PMT quartz window … Fresnel or total reflection; –Scintillation light spectrum … Monochromatic, Gaussian, Basov et.al, etc. –Rayleigh scattering/absorption in Liq. Xe.

9 Feb, To be done: beam test NaI response simulation; LiH target and Vessel simulation; Phase space simulation for  0 ; Offline database … ODB? Separate database (e.g. PostgreSQL, MySQL, etc.)?

9 Feb, Event Display - the MC event display in the unified framework will be written by using GEANT3, while for the general event display (useful for on-line also) the final decision will be taken later.

9 Feb, Schedule & Man Power (1) Present a realistic schedule by the review committee –By when will each sub detector part be ready? e.g. Is the DC simulation ready by the coming DC beam test? –Assignment?

9 Feb, Schedule & Man Power (2) Liq Xe … G.Signorelli, S.Yamada Drift Chamber … F.Cei, H.Nishiguchi Timing Counter … P.Cattaneo Target/Beam … P.-R. Kettle Magnet … W.Ootani Trigger … D.Nicolo
