Actions

Numbers continue from the existing action list [man-actions2].

34 John Seely multi-layer programme: optical Properties of Silicon-Scandium test piece at 400 Angstroms

35 Joe Davila Iridium-silicon design and testing

(30) J side debris model

(Matthew Whyndham notes: I already have information about the debris model for the orbit. This needs to be interpreted in such a way that it accurately reflects the likely damage to the front filter, and what this would mean in terms of the stray light budget for the whole instrument). 30

36 Clarence Korendyke prelaunch alignment procedure

37 NRL Mechanism tradeoff for Cassegrain and OAP - consider disturbing torques, the possibility of counter-motion for: image scanning mechanism and slit exchange mechanism and any other mechanism.

38 BU Structural tradeoff for Cassegrain and OAP - consider general structural properties (mass and distribution of mass, vibration frequencies, assembly and alignment, s/c interface details) A purged non-vacuum vessel is to be assumed.

39 RAL calibration plan, neutral lines/images for alignment

40 RAL (Barry Kent) cleanliness

41 MSSL, UCL electronics box mass and power

42 LKHM develop science notes in collaboration with J and US colleagues.

42(a) MW Provide "study sheet" in .xls format

43 Matt Whyndham iterate management plan with 3-country collaboration

44 Matt Whyndham produce draft list of interfaces with responsibilities and required data.

45 MW+John Mariska establish a mechanism for the automatic distribution of the project website.
