1. Feb CIS meeting
Marcy Stutzman

2. Cryopump work
Leybold: Summer student project. Good bake, good base pressure, open valve, repeat measurement, characterize gauges, write up
Sumitomo: BNNT working to stabilize material for easier installation
Pump speed tests need to be repeated, published
Optimize setup for capacity and speed tests, several repeats (summer student assistance if timing is right

3. Other vacuum wish list Vendors claim low outgassing rate:
aluminum (VaCom)
Stainless Steel (Andersen Dahleen)
Buy with outgassing rate already ?
No heat treatment, NEG coating needed?
New sintered (rather than rolled) NEG materials (less dust, better capacity) – have one for testing
Base pressure? Reliability?
Combine new materials, pumps for next version gun? (see price difference if we need to fabricate another 350 kV style chamber)

4. MicroMott improvements
Must
CEM replacement (on order)
Should
Reproducible stalk insertion point
Alignment for better transmission
Maybe?
Better optical bend, shorten lens system?

5. Other random stuff
Are they going to need my help modeling the JLEIC interaction region vacuum? Entire system vacuum?
How do we satisfy SRF with our UITF beamline assembly?
What else toward adding NEG pumping in warm girders between cryomodules?

6. Publication backlog NEG coating -> vacuum (in progress)
Gauge characterization
Small chamber ultimate pressure results (maybe with gauge characterization)
Cryopump test results
My parts of the Mott paper
