Dennis and David

The FDR for the AOS SLC Manifold/Cryopump and Mode Cleaner Tube Baffles has started but is not yet complete. The presentation material is at LIGO-T1100165-v2. There were two issues raised at the presentation style review that we held on the 22nd of June, items #1 and #2 below. As chair I am remiss canvasing the committee further or writing up a report on this.

The two open issues that the SLC team need to address are: -

1) Update overall porcelain coating plan and apply to designs, of which they indicate there plan below
and
2) Confirmation of the status of the status of the 1st article Manifold Cryopump baffle in terms of welds and porcelain coating.

In the mean time I would like to recommend we allow the SLC team to go ahead with the procurement of the metal components for the mode cleaner baffle's now, the details on this from Lisa can be found below. We will then hear from them separately on an updated porcelain plan AND on the status of the 1st article Manifold Cryopump baffle - thus allowing us to complete the FDR at that point.

In addition I would like to strongly encourage the SLC team to move on item #2 above. (Apologies if I have missed an e-mail on item #2 but I have yet to see details on the weld samples for the Manifold Cryopump baffle or confirmation on a visual of the porcelain coating on the Manifold Cryopump baffle at LHO.)

Cheers, Calum
