ATLAS SCT Testbeam : October 2001

ATLAS SCT Testbeam

October 2001 beamtest at CERN H8

VERY Preliminary Results

Configuration data and characterisation runs
Example online monitoring plots
Scope shots of SLOG Clock-Command Phase Difference study
Conclusion: There is a spread in phase shifts at the Slog output
Scope shots of Triggers, TTC Clock, and Beam Orbit Clock

Schedule : 15 - 31 October

Preparation of DAQ, Characterisation of Modules: 15-22/10
Installation in Beamline: Start 08:00 on Tuesday 23/10
Beam: Start During Thursday 25/10
Removal of Modules and decommisioning for 2001: (WAS Sunday 28/10) Wednesday 31/10
Extension possible if required and if personnel available

Afterwards

Viking Telescope
- Remove modules, replace in cardbox box
- Telescope Modules to Shaun, B161
- Telescope mounts to H8 cupboard
- Telescope power supplies and short cables to H8 cupboard
Trigger
- HV Off in control room
- Uncable
- Move trigger assembly to beside beamline
Modules
- Remove modules; leave short cables and some support cards in chamber
- Replace metal cover plates : leave plastic cover plates at H8
- Transport all modules and chokes to B186, barrels to Joern
- Transport some support cards to owners as per their labels
Environment Chamber
- Chillers off
- Carefully move onto the white table beside the beamline
- If possible, leave chillers connected to chamber
Cables
- Pull up onto cable conduit into neat array
VME Modules
- Return modules to owners at CERN as per list above
- Leave Melbourne V262 in crate
- Leave testbeam modules in crates
NIM Modules
- Leave in crates
- Lock with chain without damaging modules or cabling
Computers
- Make ZIP files of the following directories:
  - c:\sctdaq => e:\tbzips\sctdaq_tb31Oct2001.zip
  - c:\tbdaq => e:\tbzips\tbdaq_tb31Oct2001.zip
  - d:\sctvar => e:\tbzips\sctvar_tb31Oct2001.zip
- Copy all these ZIPs to pcatsct04:/tb/tbOct2001/
- Copy all these ZIPs to CASTOR
- Write a CD-ROM of the ZIPS
- Move pcatsct04 to a rack where it is connected to the network but not too obvious
- Leave the other PC and the HP on the tables
Cupboards
- Lock the two cupboards at the back
- Return the key to Shaun or the B161 secretary
