6 Instrumentation Operations (Bret, Friedrich, and Dave H.)

6.1 Optics

6.1.1 System Optics

6.1.2 Facility Instrument Distribution Optics (FIDO)

• FIDO blanks for the new GS30T500 and LBS940 beamsplitters were shipped to Zygo for figuring.

• The summit coude room FIDO configuration was changed by the TechOps Optical team to support all GOS light to the VTF for the upcoming January/February installation

6.1.3 Polarization Analysis and Calibration (PA&C)

• The GOS needle valve was replaced to improve the coolant flow to the GOS.
  

6.2 Summit Instrumentation

6.2.1 Instrument Systems

6.2.2 Wavefront Correction System (WFS)

• New MCAO balcony cross struts were installed to reduce vibration on the balcony.

6.2.3 Visible Spectro-Polarimeter (ViSP)

• The ViSP All-Stop behavior was changed by the TechOps team to remove the manual toggling after every GIC inhibit.

• The spectral dispersion calculations were changed to save the correct metadata in the header.

• New filter holders have been designed to reduce the amount of time needed by the SOS to swap them.

6.2.4 Diffraction Limited Near-Infrared Spectro-Polarimeter (DL-NIRSP)

6.2.5 Cryogenic Near-Infrared Spectro-Polarimeter (Cryo-NIRSP)

• Major Cryo-NIRSP maintenance activities were performed in December. All cold heads were replaced and the old ones sent to the manufacturer for service. All O-rings were inspected and replaced if needed. The cryo-compressors were serviced and oil absorbers replaced. Compressor over-temperature sensors were replaced.

• The new second grating was installed in the instrument. The second grating will be used only for testing this year.

• The instrument was closed. All vacuum testing was successfully performed.

6.2.6 Visible Broadband Imager

• Dichroic blocking filters for VBI-Blue were ordered from a second vendor following last’s last months spec specification development. Some commercial mounting hardware was ordered for both -Blue and -Red channel blocking filters. These filters should be installed before out-of-band flux is sent to VBI by the new Grey FIDO beam splitters.

• The new VBI-red H-alpha filter was installed. The old filter was moved to the H-alpha off-band position.

6.7 Multi-Conjugate Adaptive Optics (MCAO)

6.8 High Level Software (HLS)

6.9 Infrared Cameras
