Tracker20150107 Tracker Status¶

Unpacking

• Some lurking darkness with old data and new
• May be it just works (haha)
• May be possible to disable tracker (and unpack only the other detectors)
• May be possible to fix

Readout

• DATE has updated 3 times in PID DAQ, probably it's okay, not tested
• Hardware interface will still work
• DATE Equipmentlist classes not dependent on DATE but provide interface to DATE
• DATE C functions
• Compiles as standalone but not tried compiling/linking against DATE libraries

Trigger

• Old trigger is probably still production
• New trigger - no documentation
• Asynchronous veto needs to be introduced to the new trigger; trigger VME board
  doesn't have a fast enough clock to veto; Ed Overton has proposed vhdl code; no
  response from Yordan; could do something analogue external to new trigger;
  could use old trigger
• Need to check RF clock will be available

Cryostats, cabling, waveguides

• d/s cryostats are cold at 6 K which is less than 9 K;
• u/s cryostats are cooling, should have time to cycle once to clean out impurities
• d/s tracker cabling planned for afternoon of 13/01/2015
• cryostats need to be grounded
• Would like to fire the LEDs as pulsers to make noise
• Tells us that delays correlating tracker to trigger are okay and make recon
  through to space point

Controls

• Some juggling of controllers required to make everything work as CAEN spares left in Sheffield
• SVS fall back; may not be trivial to roll back
• MKS (vacuum) and temperature controllers and readout is being implemented by DL - unlikely to be in place by 21st

OnRec

• No response from Uchida re: OnRec
