Muon DT software At last muon week (3/4/2002), an overview of the general muon software status/ organization was presented, going through the different projects (ORCA,OSCAR) and subjects ( testbeam, PRS/HLT, DCS,database, calibration) See: http://cms.pd.infn.it/software/talks/muweek_0204/ file : Agenda_Intro.ppt and talks referenced therein. As far as the organization of DT software, the (current) organization is the following: CMS week, 11/06/02

DT testbeam & cosmic run data analysis A.Meneguzzo, F.Cavallo, S.Vanini, P.Ronchese, M.Zanetti, U.G. Summary: - Test beam data analysis: - mainly x-check of known results (MB2, testbeam 2001) - test of algorithms in controlled conditions... - used in cosmic test on MB3 chambers built in Legnaro - used in current local pattern rec. for HLT studies - Cosmic test data analysis on MB3 chambers in Legnaro Also special thanks to M.De Giorgi, F.Gonella CMS week, 11/06/02

Cosmic run data in Legnaro • - 4 chambers (MB3_01, MB3_02, MB3_03, MB3_04 ) have been assembled • and tested under cosmic run in Legnaro • each single SL has HV tests, pressure tests, noise/rate test, dead-channel test… • with scalers before chamber assembling => not speak about it here… • Assembled chambers are the then put on a cosmic station test • (1/2 chamber per time is tested) and a full DAQ => local rec. chain • (ORCA, running on Obj.database; all data stored/archived there) • Results (noise,cell efficiency, MT measured in cosmic runs) stored in ‘database’ • on Web (M.Passaseo, P. Checchia): • http: //www.pd.infn.it/dbcms • (also: wire position measurements in SL,…) CMS week, 11/06/02
