Hi Zhangbu et al.
According to Bill Christie, we should get access to the STAR detector
about 4 pm tomorrow afternoon.
We should plan at that time to take noise rates for the 12 modules that
are being read out. I think an "or" of the 6 channels for oeach module
will be sufficient, unless the rate is unusually high or low in which case
we might want to look channel-by-channel. We probably should also take
noise rates from 2 or 3 high-eta modules that were not included in the
read out. These modules had noise rates that were 2x the low eta module
rate but the high eta module that is read out now has a low noise rate so
we should verify if this problem has gone away.
We might also try to do some tests to see if the correlated noise is in
neighboring channels in a module.
I also would like to turn off the HV and measure the noise rate decay
in the scaler.
I have to go to JFK at 6:30 so if we don't finish by then, we will need a
TOF gas shift until I get back about 10. I can finish anything else we
want to do by midnight, then shut off the gas.
Cheers,
Geary
