¥Tuesday night
¥Switch to scintillator (cosmics) trigger
–TRT already seeing tracks
¥Started timing scan
¥Accelerate timing adjustment by using signal
threshold of 1.2fC
¥Gradually shift SCT timing and watch for tracks on
event display!
¥Wednesday morning 20 Feb
¥ realized
timing probably just out of range of SCT timing range
¥ added 3
clock delay in CTP
¥ fixed SCT
BCID FE/ROD mismatch
¥ synch
fully with CTP and TRT
¥ started
seeing tracks in final time bin
¥the first cosmic tracks were
reconstructed in SCT and TRT within hours.
