ARCTIC Notes
Attending: Joe, Bill, Alaina, Alysha, Suzanne, Russet, John Wilson, Russell

- 1. Dewar Update -- Test fitting etc. · Been going well. Have all parts. Did initial pump-down to 1e-7. There is a little bit
of oil and water which will be cleaned with an ultrasonic cleaner. Then assembly in a cleanroom. Leak test performed well.

· Ed is working on temp sensors, them temp testing. · We are working on the dewar window, will borrow from Spicam for testing. · Needed parts should be in hand by end of the week. · Joe will be back end of September to finish thermal testing before it goes to Leach
(week of October 6 or Oct 10).

· John -- might be good to get details on connectors and wires between us and
Leach? Might be good to have a wiring diagram.

- Joe says Leach will supply connector to the CCD. He could also supply
connectors and cables to his controller.

- John -- It probably has two parts. - Joe -- Plus we have two video monitors. - John -- Diagrams never hurt! Leach will provide a pump for testing? - Joe has been discussing that will all parties. · Bill -- Several of our instruments have Leach controllers and we don't use them as
Leach suggests.

- Joe -- Heat needs to be vented, so will need to install vents. - John -- we added plates for exhaust. However you do it depends on heat load.
Must allow air flow. And consider mods.

- Bill -- Are those covers on either ends for the video cards? - Joe -- Leach says yes.

- John -- You will have to modify his plates for connecting cables. - Bill -- I suspected. - John -- Feel free to poke around TSPEC and look! - Bill -- We don't want to re-make any of his cable assemblies. Doesn't look like a
ton of room to play with, so we'll see when we get it. Webpage does not show panels on the ends.

- 2. CCD Fun -- Joe · Thursday, STA said CCD was ready, and they have never heard of a new coating
for development. If we want a new coating, we must provide the CCDs to test it on. They offered to exchange if they do get a new coating. We need everything in writing!! Joe says they can coat it this week. Will they commit, or break our agreement?

· After that, Joe will have the CCD shipped to Leach, and bring dewar for integration. · This coating (Curve B) may lose some in the red, but may not be too bad. We will
need an ACTUAL plot for our CCD, not a theoretical one. This may cause problems, because the PR has no benchmarks for them to meet.

· We hope that they will not put their reputation on the line by not delivering as
advertised. Hope for good news in a week or two.

- 3. Other? · Suzanne -- Schedule question. Chip is in the dewar and comes to APO around Oct
25? Computer as well (Bill will get on Fritz). Then bring to Seattle?

- Joe says yes. He will perform tests there. Would like Bill to come up. - Then Russell and Conor have access beginning of November. · Joe -- Russell, do you have all the docs you need, or do you need more? (email,
Sept 3rd at 9pm)

· 64 bit processing, verify with Fritz. · Joe -- Optics vendor declined the bid, too risky. Bit to NewTech but will be a week
or two for a quote. Alternates? Talk to Carnegie, and Magellan. Robert Barkhouser. Don't let the vendor say APO supplies the material. Ask how comfortable they are with the material.
