Shekhar reported that he had had a meeting in the morning with physicists from the CKM experiment. A couple of them joined us to discuss new demands on the Main Injector with a goal of exploring what we can know in time for a P5 (HEP Planning) Committee review on March 26. The experiment has Phase I approval from the Lab based on a request for 120 GeV slow spill from a debunched proton beam of 5E12/second with 6 batches. With delays in LHC and NuMI schedules, there is interest in running CKM in alternative modes. For example, delivering their spill only every few MI cycles but with up to a six second flattop at 120 GeV on their cycle. What about kicking out some beam for NuMI while preserving beam for CKM slow spill. Some issues were discussed and questions assigned:
The RR22 transfer line BPM's have been timed in. Will try to do calibration of Schottke detectors vs. scrapers during the week. The new box to provide emittance monitor outputs continuously will be available next week. Vacuum in the worst areas near the flying wire boxes is still 1E-8 but getting better. Vacuum group is examining the removed flying wire components at E4R. Before they can have results they will have to fire the TSP's, turn off the turbo's, and turn on the ion pumps. Clearly there is some hydrocarbon involved. Expect and answer by end of the week. In order to protect the Shottke electronics, we will put an alarm on the 621 losses. [Losses had been bad because someone stepped on the beam pipe -- now fixed.] Shekhar asked for a tight limit -- choose 1 volt on the LM621.
Bill Foster provided a brief update on the MI Damping system upgrades. Brajesh Choudhary informed us that the response of the MI BPM review committee has been provided from Mike Martens. It was suggested that the Tevatron requirements be compiled so that compatible systems can be created. He also announced that the PO for the RR BPM electronics cards has reached the vendor.
