---+++ April 9, 2008 NGS Engineering ---++++ Goals The Palomar AO system has recently undergone a significant refurbishment. In the 4 months since November 29, 2007, we have: * Recoated the AO relay flats and OAPs, and repolished and recoated the DM. * Realigned the AO relay to provide a focus suitable for P1640 and SWIFT. * Mounted FM3 on a removable kinematic base. * Modified the PHARO mounting cradle to move PHARO forward 4.5". * Modified the AO enclosure and added a PHARO FM3 enclosure. * Installed a new AO stimulus, with 594nm laser source. * Installed a new motor controller for Aerotech stages. The purpose of this engineering night is to demonstrate the readiness of the refurbished system for NGS-AO science, and to characterize its performance. ---++++ Personnel and engineering schedules Planning to be present: Angione, Baranec, Bouchez, Burruss, Roberts, Troy.<br> Engineering schedules: ---++++ Procedures and test plans Please post your test plans on the [[TestPlans][Test Plan Library]] page, and add a link below. * Daytime tests * AO bench setup and checkout (2 hrs) - J. Roberts * Tune image on PHARO * Check centration of field stop. * Check AO to telescope pupil alignment. * PHARO pupil motion (1 hr, telescope operator required) - A. Bouchez * Stimulus/AO system flexure (1 hr, telescope operator required) - R. Burruss<br> * Demonstrate WL acquisition at all zenith angles. * [[http://www.oir.caltech.edu/twiki_oir/pub/Palomar/PalmLGS/TestPlans/palao_pharo_flexure_v1.pdf][Test Plan]] * Nighttime tests * SSM motion and pupil registration (1 hr) - J. Roberts. * SSM range, pupil/image motion control, centroid to pupil motion gain) * Demonstrate new registration & flatmap routines (30 min) - J. Angione * Closed-loop performance (3 hr?) - A. Bouchez / J. Angione * Good seeing/Stable transmission. * V=6?, 8, 10, 12, 14 * Test reconstructors? * Predictive AO data (10-15 min per data collection, multiple times per night (3-4) if possible) - M. Troy. * Test Plan - [[http://www.oir.caltech.edu/twiki_oir/pub/Palomar/PalmLGS/TestPlans/PALAO_predictive_ao_V1.1.doc][doc]], [[http://www.oir.caltech.edu/twiki_oir/pub/Palomar/PalmLGS/TestPlans/PALAO_predictive_ao_V1.1.pdf][pdf]] * Throughput (1 hr; clear) - R. Burruss. * [[http://www.oir.caltech.edu/twiki_oir/pub/Palomar/PalmLGS/TestPlans/palao_pharo_throughput_v1.pdf][Test Plan]] * Platescale (PHARO, ACAM, LOWFS) (1 hr) - A. Bouchez * Test Plan * [[binaries_080409][Target list]] ([[http://ad.usno.navy.mil/wds/orb6/orb6c.html][Calibration binaries]], 2-15" separation) * Field distortion (30 min?) - B. Cameron / R. Dekany * Flexure (1 hr). * If daytime test shows significant flexure.
