* Type B Past Week Summary * Mark (with Enzo) did initial TFs on the BF. * Did fixed-sine TFs on individual OSEMs at low frequency to check actuator polarity (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2176 | 2176]] and [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]). * Set gains in the COILOUTF block to compensate for actuator polarity. * Mark (with Enzo) did a free-swing measurement on the BS after earthquake of 11/22 (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]). * Results suspicious (noted by Shoda-san): too much difference between OSEMs - horizontal showing much less motion than vertical. * Possible rubbing in horizontal. * May need a trip to Kamioka. * Mark (with Enzo) made corrections and improvements to many of the MEDM screens (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2176 | 2176]] and [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2182|2182]]). * Main overview screen was not generic in many places, and links to GDS_TP screens were broken. * ADC monitor screen referenced bad channels with LIGO-style names. * DAC monitor screen was not generic and did not support IM OSEMs. * Watchdog IM OSEM AC band limit filter screen was a copy of the TM one. * Watchdog TM OSEM AC band limit filter screen appears to be getting OL signals as input - needs model changes to fix. * The zoomed screens for IM OSEM centering were called incorrectly and did not work. * Various screens had LIGO-style channel names as labels. * Mark did a draft of D1603600-v12 reflecting the new assignment of IM OSEMs to DAQ channels (#4-9 are now V1, V2, V3, H1, H2, H3 rather than H1, H2, ...) from last Friday (the wiring was changed to reflect the model). * Mark worked on schedule. * Hirata-san |
