Testing of the optical bench has completed. All anomalies
have been traced to test setup issues, with the result that
the bench meets or exceeds performance requirements in all areas.
These additional tests have delayed the bench shipment to Ball
which had been scheduled for the end of this month.
An internal project integration readiness review was completed
for the Ball activities in the coming months.
The IR filter followup telecon for the Filter Milestone Review
was completed successfully.
All IR filters are received from the vendors.
UVIS filter deliveries continue to be a challenging area. In
particular, the UV filter design with epoxy fill is suspected
to be the cause of throughput degradation, and an air-gap design
is being developed.
Some of the requirements on the narrow-band UVIS filters have
been relaxed to help expedite delivery.
A CCD Process Review was held to examine the processing risks
for installing the Marconi detectors into the Ball enclosure.
The recommendations are being incorporated into our planning.
A few weeks of the Marconi CCD testing for the high temperature
soak had been at 150C instead of 110C. This has been corrected.
The intermediate results look very encouraging, with little
change noticeable after 2 weeks of high temperature soak.
IR FPA #18 has completed characterization, and was shipped
to Ball for the IR Qualification Enclosure build.
The Optical Stimulus work has moved from the GSFC Building
20 SLAC facility (deintegration and metrology) to the Orbital
facility in Beltsville for reintegration and testing.
