PROGRESS REPORT
July
26 – August 31, 2002
Accomplishments / Status
Summary:
92% of the work from the Restart Review to delivery has been completed.
Progress was made on radiation shield assembly rework, bench assembly,
fit checks and wiring, and slit mechanism cold testing. The Project Manager
now projects delivery of the instrument for March 2002, while the Work Package
Manager believes the Pre-Ship A/T will be completed in Tucson in June 2002.
The 9th Quarterly Review is scheduled for September 3rd.
The last SR camera lens has been returned to Janos for repair and recoating. This camera lens should be returned in early September, and will be cold-cycled before installing into the camera. Flexure testing is scheduled for early October, following completion of instrument assembly and initial testing. All mechanism testing is complete.
The instrument is scheduled to ship to Chile in the first quarter of 2003.
Next
Milestone: The next major
project milestones are:
- Top assembly integration –
September
- Warm tests with Mux -- September
- Flexure testing – late September-early October

Deliverables: (54% complete overall)
Work
in this area has focused on the Software Maintenance manual, which has been
submitted to Gemini for review. Draft manual outlines are complete for the
Hardware Maintenance and User’s manuals.
These are ready for submission to Gemini.
Procurement:
(99%
complete overall). SRC lens is
scheduled to return from Janos rework on September 10th.
Other open items are miscellaneous parts and supplies.
Problems / Solutions
SRC
camera lens required rework by Janos, and will be cold cycled to insure
structural integrity before installation in the camera.
