HPT status hardware

A large data set of test pulses was collected last week, revealing 0.5% dead channels and 0.2% hot channels under no magnetic field conditions. Slow control, power, and data taking were successfully tested. Plans include adding more slow control data, ramping up HV, switching on gas pre-cosmic run, and taking more cosmic data in May without magnetic field for the upcoming collaboration meeting in April 2009 in Aklara. Updates on software status, alignment, drift tube alignment by Irina, time alignment ongoing, new charge determination version prepared, momentum determination ready, beam contamination studies in progress, and reco status as discussed by Björn in the previous physics meeting will be presented.

Presentation Transcript

  1. HPT status hardware • large data set of test pulses taken last week (remote)  0.5% dead channels, 0.2% hot channels (without magnetic field)  thus slow control + power + data taking tested • adding more slow control information into data base • ramping up HV next week • switching on gas short before cosmic run • taking more cosmic data without magnetic field in May ready for next run period collaboration meeting, April '09, Aklara

  2. HPT software & analysis status • alignment  see talk of Irina about drift tube alignment • time alignment (trigger timing) ongoing • new version of charge determination sent to Antoine, internal note in preparation • momentum determination ready • beam contamination studies ongoing • same reco status as presented on last physics meeting by Björn collaboration meeting, April '09, Aklara
