Presentation Transcript

  1. Upcoming Dates Accumulator Ring: • ASAC Review September 24 • Collimator/Extraction Area/Design Reviews /Installation October 9, 10 • FY2003 Budget issues • Magnet Specification List – Individual Magnet Parameter Sheets • Meeting Friday 10/4 1:30 p.m. – S. Tepikian and M. Hemmer • Review them and SIGN THEM OFF • Monthly Report Today • DOE Review November 13

  2. ASAC Review Ring specific comments presented by the committee: • Findings and fixes (shimming) on magnets are in good progress -- continue. • It would be good to verify proper field in the presence of vacuum pipe (e.g. HEBT magnet measurement with beam pipe although Ted claimed the pipe non-magnetic. • Good to see ring half cell to be tested and delivered to ORNL; looking forward to it. • RF work as presented is well done. • Vacuum work as presented is well done; more to go. • Looking forward to see planned, detailed field measurement of injection chicane magnet near H- electron stripping foil in comparison with 3D mapping. • Endorse the proposal of a new view port and video monitoring of carbon-carbon electron collector near injection. • Good work is done on impedance reduction of the extraction kickers; more needs to be done on impedance measurement of RF cavities. • Continue to explore beam loss mitigation • Fast feedback, as presented by J. Galambos, can be tried e.g. to position beam on the stripping foil • Electron cloud: (a) procure and install elements that can disturb ring vacuum system, including clearing electrode at injection and solenoid windings at collimation section (b) procureother devices as budget allows • Comments on collective effects and others are to be included in the written summary (not presented).
