H4/SPS Daily meetings
September 6
Status: First day of beam. We were supposed to have the beam at midnight, we got it at 3PM. The timing was looked at, the calorimeter signal is now coming earlier with respect to the tracker as compared to PS. BT 5 configutation with cal/tkr in the middle of the trigger window at SPS is now the baseline.The calibration of the calorimeter (cross pattern) at 100 GeV was started then interrupted to let the experts optimize the beam tuning at the highest energies. Many interruptions due to machine problems.
Program: completion of the 100 GeV calibration runs, ACD calibration with protrons+pions, switch to 200 GeV, scanning of different (X,Y, theta) configurations
September 7
Status: Calorimeter calibration completed, ACD calibration completed, scanning of 200 GeV configurations almost completed. The dependence of the calorimeter measured energy as a function of rate has been investigated ("baseline restoration" problem). The effect is clearly visible. We decide to limit the rate to 400 Hz.
