Progress Report - April 24 to May 24, 1999
Accomplishments / Status
Summary: Good progress continues to be made on the instrument repackaging effort, particularly on the Main Bench Assembly and mechanisms. The May 10 Interim Design Review is re-scheduled for May 25. The Restart Review is still scheduled to be held July 20-21. Current updates on the GNIRS project are available on the NOAO/GNIRS web page <http://www.noao.edu/ets/gnirs>.
Optics: The update of the GNIRS optical design is 75%complete, and will be finished in early June.
No progress has been made on negotiations of the II-VI optics contract. Current plans still call for procuring the Offner primary and secondary and collimator mirrors from II-VI, and using a different technology for the flat mirrors. The final decision on which optics technology to use for the flat mirrors and whether to pursue alternate sources for the Offner mirrors will be made in early June.
RMI will be authorized to start lens fabrication after the Restart Review.
Mechanical Design: Preliminary designs of the Pre-Slit optics Bench, Wavefront Sensor Bench, and Main Optics Bench nearly complete. Preliminary design of the Slit-Decker, Cross-Dispersion Turret, Grating Turret and Camera Turret mechanisms has been started.
Mechanical Fabrication: Instrument component fabrication, except that needed to support prototype testing, is planned to start in December ’99 – January ‘00. The Test Dewar, being provided by NOAO, is complete, and characterization testing is in process.
Cold motor qualification: Evaluation cold testing of Portescap motors is completed, and testing of Phytron motors is in process. Portescap #P530 motors have been disqualified for use in the GNIRS due to poor performance during evaluation testing. Initial testing of a sample Phytron motor from Gemini (as used in NIRI) has yielded good results. Delivery of the specific Phytron motor selected for use in GNIRS is due to be delivered on May 28. The Phytron motor has been baselined for use in the instrument.
Electronics Design: Electronics systems information is now installed on the web site and may be viewed at <ftp://ftp.noao.edu/gnirs/elect>
Software: No activity.
Problems/Solutions:
Software Engineer: The March report stated that an individual experienced in EPICS needed to be identified and assigned to the project. We are still working on a solution to this problem.
Key Personnel:
Andy Rudeen is working at the 20% level the COB for Gemini effort.
This is an approximate 6-month assignment, which has no detrimental effect
on the GNIRS project.
