Attended cryo-integration meeting

Report on some of the main points given in the meeting:

- Cryo-payload-integration meeting will be held only once per month in this FY

- NAOJ groups should attend the meeting (VIS, AOS,...); respective requests will be given later maybe

- No clean booth this FY because of financial problems

- NAOJ should consider to construct a clean booth on the second floor


- one payload will be purchased this year (have to!), then checking; others next year

- surface polishing of sapphire-sapphire ear connection area by impex not sufficient (P-V=633nm/2 is required but 1.4*633nm measured by Tatsumi-san)

- Other black material: oxidized, rough copper surface.
