DEIMOS THE INSTRUMENT PROJECT OVERVIEW Wednesday, August 17, 1994 Present: Business Office Staff, Shop Staff, Optical Staff, Engineering Staff, Electronics Staff, Deanne Lago. DEIMOS = Deep Imaging Multi Object Spectrograph Deimos is designed as a double sided (barrels) rotating visible light spectrograph, which will be at the Right Nasmuth of the Keck II telescope in Hawaii. Principal Investigator (P.I.) for this project is Garth Illingworth. Co-P.I.'s are Sandy Faber, Harland Epps and Joe Miller. As a group the P.I.'s have broad oversight and authority over the project. They set scientific goals and the detailed performance specifications that flow from them. They make cost/performance trade-offs after being informed of budgetary and technical consequences by the Project Manager, David Cowley. They are responsible for assembling the financial resources needed to complete the project. The instrument will be designed, fabricated and tested here in the UCO/Lick Labs in Santa Cruz. Deimos will be able to view approximately 150 spectra at a time. Presently funding has been obtained to build one side of the spectrograph, but we anticipate funding to come through for the other side by this time next year. This project officially began July 1, 1994 and is scheduled to be completed in August of 1998. During the course of this project UCO/Lick will still need to commit to doing other projects as well. Therefore scheduling of manpower is critical to the success of this project. (A detailed schedule was handed out at the meeting.) It is anticipated that this project will need at least 60,000 man hours to complete. Deimos is designed to be 13' long with a 6' diameter and is expected to weigh 6-8 tons. It will rotate opposite to the rotation made by the telescope. This instrument uses several mirrors, grat- ings, cameras and two Charged Coupled Devices (CCD's). There will be several reviews of the design, optics and software prior to completion of the project. A full sized model will also be built in our labs during the next few months. The first review is the Preliminary Design Review which is scheduled for November 1994. This will be followed by a Critical Design Review approximately one year later, with the Critical Software Review in April 1996. The purpose of these reviews is to invite outside parties to look over our plans, ask ques- tions and determine if this instrument will work and can in fact be built on our budget.. A detailed budget has been established and cost codes have been created to accompany almost every option. David Cowley must sign off on all orders and anything over $5,000 must also be approved by one of the P.I.'s. Travel must also be approved in advance by Dave.
