* 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, including: * 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). * Information on how to identify the wires from the steppers and LVDTs so that the adapter cables can be plugged in properly. * Mark worked on schedule. * Hirata-san did drawings for new 8-mm maraging wires for Type A. * Hirata-san worked on PR/SR mirror box modifications with Shoda-san. |
=== Type B (Mark) === ==== Past week report ==== * We brought the SR2 optic into the tunnel and moved it into the good mirror box. The spare mirror was moved into the not-so-good mirror box. * Enzo assembled the SR2 rack and laid all the long cables from the rack into the cleanbooth. (Hayakawa-san can now proceed with the rebuilding of the changing cleanbooth.) * Mark and Shoda-san took data for calibrating and diagonalizing the OL. (Due to the odd angle of the first steering mirror, the beam pattern is rotated by 62° at the QPD.) * Enzo found nearly all in-vacuum cables. * Enzo and Shoda-san got several more loops closed on the BS. * Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4). * Mark took out S-numbers for anonymous boxes in the SR2 and put yellow stickers supplied by Tomura-san on them. * Hirata-san worked on SR procurement. * Hirata-san worked with Mirapro to get the SRM LBB installed in the tank. ==== Plan for week of 12/4 ==== * Mark at Kamioka. * Fabian at f2f satellite meeting Mon, then Kamioka. * Enzo at f2f then Mitaka. * Hirata-san at Kamioka Mon-Thu, Mitaka Fri. * Kozu-kun Thu only. * Mirror gluing. * IM assembly and pico test. ==== Plan for week of 12/11 * Mark, Fabian, Enzo, Hirata-san, Shoda-san at Kamioka. * Kozu-kun Mon-Thu only. * Assembly frame alignment and optical table centering. * Move trolley system from SR3. * OL setup. ==== Plan for week of 12/18 ==== * Shoda-san vacation * Mark, Fabian, Enzo, Kozu-kun at Kamioka Mon-Wed. ==== Vacation Info ==== * Mark 12/22-1/3 * Enzo TBD, probably 12/22-1/3 * Fabian 12/22-1/5 * Hirata-san 12/21-22 (conference) * Shoda-san 12/18-21 |

- Enzo found nearly all in-vacuum cables.
- Enzo and Shoda-san got several more loops closed on the BS.
- Mark found three geophone pods and two feedthrough adapters for SR2 (now have 3 FAs but need 4).
