Report
MMTF Test and Support
- modified clear cover to be used with assembly
- oversaw installation of MMTF
- designed new cover plates that include plexiglass holes for covered bench tests
- drafted plans for fixture to mount Hg light box to the uprights
GISMO Mask and Tooling Testing
- assembled tooling components and mask blank
- installed in laser cutter, no issues
- test cut a GISMO mask, several code revision were necessary
Shack-Hartmann Image Motion Issues
- Postponed due to personel issue.
Miscellaneous Maintenance and Other Work
- assembled the GISMO grating
- examined the mask door - few more incidences could result in it shearing off completely
- installed the new guide pins on the dewar - the lock-pin hole was enlarged
General Notes
- Design a matrix ring cover that protects the ring from contact with paint fingers when being stored or manipulated. The cover could be aluminum and pick up the pinholes and jack screw holes on the ring. The cover plate will be designed with a short boss/insert.
- One set of shutter cables, from instrument bulkhead to shutter bulkhead, is being used for both camera shutters until the cable issue is resolved.
- One f/2 shutter motor assembly has been installed in the f/4 shutter and visa versa.
- Items Arriving LCO:
- GISMO 150l/mm grating
- MMTF halpha filter
- MMTF Krypton Penray
- pinhole camera aperture plate and 50 um pinholes (4X)
- shutter blade/block mounting hardware
- spare shutter cables
- spare FSS air cylinders (3X) - these could be the wrong model
- Required Parts
- new MMTF cover plate
- matrix ring cover plates
- MMTF Hg light box mounting jig
- bellville springs for mounting shutter block
- Future Work
- repair faulty shutter cables
- SHGC optics motion investigation
