Muon DT software

At last muon week (3/4/2002), an overview of the general muonsoftware 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:

DT testbeam & cosmic run data analysis

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

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):

(also: wire position measurements in SL,…)
