FUV Focus
• Recent analysis suggests that we are not at
optimal focus on the FUV channel – best
measurement to date is R ≈15,800
• Planning for an additional focus sweep for
G130M and G160M using a brighter target
with narrower lines
– Expect to choose a new target by COB
tomorrow so it can be scheduled as soon as
practical
5
1149271 FUV HVNom
Modification Test
• Divot and clod disappeared (shown last week)
• Relative throughput loss of at most a few percent
• Team agrees that nominal HV levels should be
permanently lowered to 169 (segment A) and 167
(segment B)
• Sent an email to GSFC last night requesting that
this change be made
6
11515 Light Leak Test
• Quick look analysis shows no obvious increase in
count rate while lamps are on
