Magellan Telescopes Observatory Report

1. Magellan Telescopes Observatory Report • Personnel • Accomplishments • Observing Statistics • Common Problems • Work in Progress

2. Personnel • Jorge Bravo has been hired as a new Instrument Specialist • Victor Meriño Has been promoted to Instrument Specialist. He will begin working in the new position as soon as the new telescope Operator is trained • Mauricio Martinez has been hired as a new Telescope Operator and will begin working on September 27 • Jorge Araya has been hired as a new Telescope operator and is now in training • Felipe Sanchez has been promoted to Programmer and will begin in his new position after training the new telescope operator

3. Accomplishments • Three M1 cell Hard-Points in Clay were removed and serviced • Work continues on the actuator air cylinder repairs • Complete service of Enclosure Trucks and Drives Both Enclosures • Designed, built and installed the LDSS-3 cable wrap and designed and install the Guider cable wrap • Installed IRMA, U of A 225 GHz and Ohio State PWV sensors

4. The new LDSS-3 and guider wraps

5. Accomplishments (cont.) • Iodine cell for MIKE installed on retractable arm (Dec) • Software control was implemented in July • S-H tests carried out at NASE and NASW ports to characterize collimation of M1, M2, and M3 (Dec, Jan, Mar) • Adjustments of M3 tilt made in March and later have significantly decreased focal plane tilt • Testing continues as weather and time permit

6. Accomplishments (cont.) • Plan developed for long-term systems administration • Internet access will be through CTIO (instead of the Chilean telephone company) • The transition to CTIO system administration is underway • El Pino and LCO network and fiber backbone upgrades are underway • All new computer installations are being done by CTIO

14. Most Common Problems: Telescopes • Primary mirror support (mirror panics, faulty actuators, hard point actuators) • Campaign underway to seal air cylinders in actuators; redesign of actuator electronics cards in progress;~50% of all time lost on both telescopes is due to these problems (but improvement is being seen) • Leaking hard point breakaway seals cause primary mirror crashes • Faulty connector on Hard Point #2 LVDT sensor

15. Hard Point #6 in Clay cell

16. Hard-point Breakaway Assembly Hard Point Breakaway Cylinder

17. Problems and Failures Enclosures • Shutter structure on Clay is scheduled for the October and November Engineering runs • Enclosure Truck Bearing failures • Louver seals • Wind Screen & Moon Roof drives • Rotating interface seal

18. Bearing failure on Baade enclosure truck

19. Work in Progress • Telescopes • Actuator leak repair • Hard-point breakaway leak repairs • New actuator control cards • New PWM amps on rotators (on hold) • M1 thermal control mixing valves

20. Work in Progress • Enclosures • Louver seals • Enclosure Truck bearing failures • Rotating interface seals • Windscreen & Moon roof drives • Rotating seal (Baade)

21. Work In Progress • Software • M3 Tip-Tilt automation • Code normalization, ini files • Translate Fortran to C++ (enclosure) • Windscreen & Moon roof automation • EDS query tools • PWM Amps, Rotator guiding, servos • M1 thermo control servo
