We moved TM1 to ITW today, I connected TM1 to ITW, and started all turbo pumps this afternoon. TP4s is very difficult to bring to 38 KRMP now. I have to use soft start model and tried twice to get this pump started (1.5 hours). This pump always had a difficult start time during the past 2-3 runs. I talked with Friedhelm and we think it should be replaced after this run. I will issue an e-fault on this pump and try to get a new pump from vacuum group. It will take 2 hours to change this pump. I could do this job with another person help. Or, vacuum group could do it. Don can schedule a time for this job before next run. Anyway, it should work fine for this run. The water interlock check related to TM1 is done. I will do the rest before blocks on. All TM1 water signals are strong and good. All vacuum gauge readings are good so far(below5.0xe-5 torr).
