Main Activities
Front End Electronics
‘Dry’ testing of sectors w/o HV started
Laser system
Shipped today, to arrive 24.4.
About 1 week (incl weekend) to install and align A-side
Cabling
Gas system
Accorde
Drift HV 100 kV (Heinzinger) installed, test with DCS
ELMB pt1000 sensor system:
Sensors cabled up 90%
TB 19.4.06 Peter Glässel, Heidelberg 4
Accorde is
in place
Next: complete cabling, setting up trigger

Gas system
Gas commissioning started Re-commissioning complete functionality (after software upgrade)
With new gas lines (modifications on plug) and dummy volume
Improvements on filling cycle: try to speed up filling cycle by using higher pressure, lower temperature on CO2 absorber
TPC gas lines prepared for switch to gas system
Start gas system with TPC end of week, filling next week (expected to take 2 to 3 weeks)
→ mid MayClean room part of system

TRD/TPC heat screenDesign done
0.5 mm Al panels with Al water lines (avg 1% X0)Fixed to SF from TPC side with bolts welded to SFWater manifolds along axial SF beams
Bidding ongoingInstallation before TRD installation (June)

Summary
Commissioning started
A lot to do before we see the first tracks

Pre-Commissioning plans, SLXL2
Commissioning of gas system from 20.3. to ~19.4.Commissioning of Field cage, FEE and ROCs
DCS systemDrift HV Laser ROC HVGatingReadout chainTrigger for cosmics, laserOnline monitoringVerify each sector, at least with laser tracks
Tracks (laser, cosmics) with 2 sectors (joining, opposite, …)Commissioning of temperature sensors
Move to UX25: 4.9.06
