TPC Commissioning plan worked out with L. Musa and P. Glassel pbm Fri., April 2 1, 2006 Current Activities Front End Electronics ‘Dry’ testing of sectors w/o HV started Laser system Will arrive 26.4. About 1 week (incl weekend) to install and align A­side Cabling Gas system Accorde Drift HV 100 kV (Heinzinger) installed, test with DCS ELMB pt 1000 sensor system: Sensors cabled up 90% General Plan from May 10 on, commissioning with shift crews each shift: 3 people begin with 1 shift/day, adjust according to progress detailed planning every Wed. safety aspects very important ! oxygen monitors, always 2 people to work with detector, no detector running w/o shift crew, ... Hardware commissioning Commissioning of gas system from 20.3. to ~19.4. Commissioning of Field cage, ROCs, ... DCS system Drift HV Laser ROC HV Gating circuits Readout chain Acorde Trigger for cosmics, laser Online monitoring Verify each sector, at least with laser tracks Tracks (laser, cosmics) with 2 sectors (j oining, opposite, …) Commissioning of temperature sensors Mechanical integrity of cooling circuit Commissioning objectives I ● Field cage ● Gas tightness of all volumes ● VHV system ● ramp­up and down up to 100+ kV ● connection to DCS and DCS functionality ● test of UPS system ● ROCs ● turn on HV with gain 5000 (from database) ● evaluate gating grid functionality ● pulses with laser ● pulses with cosmics st ● for 1 configuration (sector 6 and 12): ● measure gain and noise characteristics as fct of HV
