Summer Shutdown Activities (1Dec92) (from KPNO, NOAO Newsletter No. 32, 1 December 1992) This past summer shutdown on Kitt Peak involved a record number of projects. The schedule was extremely tight, with little room for error or delays. Our thanks go to Bruce Bohannan and Tony Abraham for their careful and detailed planning of the work to be done during this time, and a special "thank you" is sent to the many people from the mountain and downtown staffs who worked with cooperation and enthusiasm to get all of the projects completed. A brief list of the summer shutdown projects is given below. 4-m Telescope Prime focus pedestal maintenance Realign f/8 secondary mirror Install new f/15 mirror assembly General telescope wiring maintenance Survey building foundation for differential settlement Install closed-cycle cooling system for SQIID Test prototype servos for new control system Install new RA and Dec encoders Repair dome seals SQIID system test run Optical alignment and new pointing map 2.1-m Telescope Guider maintenance Re-aluminize primary mirror General telescope wiring maintenance Replace console room floor Install automated clamp for #3 mirror Clean dome and telescope Repair dome leaks Optical alignment and new pointing map Coude‚ Feed Repaint #2 tower Replace grating motor power supply New pointing map Software check 1.3-m Telescope Repair dome leaks Clean dome and telescope General telescope wiring maintenance Install new secondary mirror shims Install new RA and Dec final limits New pointing map 0.9-m Telescope Guider maintenance Repair dome leaks Repaint dome Service secondary focus mechanism General telescope wiring maintenance New pointing map David De Young
