12/30/96 Pumpdown begins for HRMA / HETG / LETG / HXDS (Phase 1 part II) calibration.
12/29/96 Vertical actuators installed, shutter actuators lubricated.
12/24/96 8 am: repress underway.

12/24/96 7 am: shutters performed less well at 65 degrees.
12/23/96 5 am: shutter test at 50 degrees shows some shutters moving slower on progressive iterations. Chamber will be warmed to 65 degrees for repeat of test. OTG & cover actuators working well.
12/22/96 11 pm: LETG first light.
12/22/96 10 pm: HETG first light.
12/21/96 shutters proving to be sticky and problematic, particularly shell 3 bottom.
12/20/96 2:40 am: HRMA first light. Detailed analysis awaits, but qualitatively, the optics look great. Low scattering indicates optics are clean, images nice and round, offloaders appear to be working very well, image taken after a rough focus is nice and tight.
12/19/96 10pm: Pumpdown went quickly, making background and other fiducial measurements while allowing time for thermalization and further chamber evacuation prior to HRMA exposure.

12/19/96 8:20 am: Pumpdown begins for HRMA / HETG / LETG / HXDS (Phase 1) calibration.
12/18/96 5:30 pm: Expect pumpdown at 7 am Thursday, 12/19. Dome is going on now. Kodak has secondary thermal system operational, primary system data will be analyzed during this short vacuum period. Remaining work included exposure of gratings and final chamber closeout (IC door thermistor connections and contamination monitors).
12/17/96 8pm: Smallest actuators on HRMA shutters are fully exposed, definately lubricated with only good tribolube. Largest actuators definately bad, though they did pass 1238. Best combination of cleaning and re-bake under discussion. Medium sized actuators which control HRMA horizontal motion, contamination covers, and OTGs, under some suspicion. Spare actuator in this size checked, lube sample taken, found to be good tribolube. All installed actuators are cleared for pumpdown. Pumpdown further delayed 24 hours by intstallion of shim on OTG brackets and delayed indefinitely by shakeout of HRMA thermistor and thermal panel wiring.
12/16/96 8pm: During checkout of vertical actuator with broken gearbox, hydrocarbon oil was found. All vertical actuators will be removed and cleaned, during this time, a short calibration will be run, with only on-axis measurements. The HRMA will be aligned and fixed on-axis.
12/16/96 8am: EKC has replaced all actuators one by one. Front actuator, which drives theta-Y, most valuable for calibration, entirely replaced with spare actuator.
12/15/96 5 pm HRMA & HXDS rolled back out, worst (suspected broken) actuator removed. Gearbox was broken, probably cause insufficient lubricant left after bakeout.
12/14/96: SAO competed aperture map, EKC testing thermistors and actuators. Noisy actuators discovered, one probably damaged.
12/13/96 1pm: HXDS rolled into IC.
12/13/96 10 am: HRMA rolled into IC.

12/07/96 6am: HRMA aft door proving difficult to align to aft contamination cover. Offloader brackets interfering with pins on ring used by alignment tower offloader. Clearance holes being machined in brackets.

10/04/96 FAM settle time tested with stair/step pattern.. FAM showed negligable settle time.
10/02/96 0700UT Phase 2 Rehearsal resumed.
10/01/96 2300 UT: 9/30's FAM problems caused a cable to restrict y-axis motion. A vacuum break was declared. Today, the cable was re-dressed, and in addition, the FAM encoder lights were blocked so that the FAM could be left on without leaking light to the ACIS-2C. An ACIS-2C nitorgen leak was also repaired; this leak caused the chamber to run at a vacuum level about an order of magnitude higher than usual.
09/30/96, 1200UT: Spent last 12 hours checking out ACIS-2C and HXDS with EIPS/Al-K source. HXDS BND-H Z stage still stalling under vacuum, but sucessfully took beam map. Preparation with ACIS-2C included light leak search, found that FAM encoders were a problematic light source. This means shutting the FAM down and zero'ing encoders to reduce background for each measurement.
