## 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).
