We called and left a > message to ITD. ( This happened at 2:30 ) Two mistakes: 1) the terminal is maintained by RHIC, not ITD. If it breaks, call the MCR and they will send somebody to look at it. 2) cycling the power on the *monitor* has no effect on the terminal. Most likely it hung and cycling the power on the *terminal* would have had fixed it. > QUESTIONS : > Should fb1, fb3 be included in the fb & camac pedestal > runs ? - yes, please include fb1 and fb3 in all runs (not just pedestals). both are fully operational and I would like to excercise them. > Should the anode voltage be on the TPCs when we are doing > pedstal runs for the TPCs ? - pedestal runs should be taken *at running conditions*, i.e. with all regular high voltages turned on. This is because the pedestals program measures the noise levels in the TPCs. The noise levels are lower than nromal when high voltages are off so the pedestals program will measure thew wrong numbers, unsuitable for data taking. -- Konstantin Olchanski Physics Department, Brookhaven National Laboratory, Long Island, New York olchansk@bnl.gov
