The Restart Review is scheduled for July 20-21. Any additional work will be scheduled as part of the regular project effort, which commences after the Restart Review. The Offner primary, secondary and the collimator will all be diamond-turned alumniplated mirrors with protective coating to facilitate handling during assembly and alignment. The remaining flat mirrors will be glass. RMI will be authorized to start lens fabrication after the Restart Review.
Preliminary design is nearly complete.
Details need to be completed for the Main Optics Bench, the Wavefront Sensor Bench, and for several subassemblies. The Preliminary Design effort will extend past the Restart Review through the month of October. Instrument component fabrication, except that needed to support prototype testing, is planned to start in January 00. The Test Dewar, being provided by NOAO, is complete, and characterization testing is in process. Testing is not yet complete on this smaller motor, but the larger Phytron motors provided by Gemini for preliminary evaluation have been successfully tested.
