| * Mark and Fabian debugged the rubbing issue with the BS. It turns out the EQ stops between the IRM and IM are so misaligned that they can't be used at all. This misalignment was noted on 10/17 klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=2090|2090]] but seems to have gotten worse. With the stops removed, the OSEMs are still fairly well centered, so the problem probably predates the earthquake of 11/1. * Mark worked on the PR2 rack: * Rearranged the items in the rack to make space for new AA and AI chassis at the bottom near the IO chassis. * Replaced the AA chassis, which had had a group of channels marked as bad by Michimura-san. * Installed a second AA chassis and a second AI chassis in the rack. * Installed a second ADC card and a second DAC card in the IO chassis. * Modified the k1ioppr2 real-time model to recognize the new ADC/DAC cards and also the extra DIO cards installed previously. * Attempted to modify the k1visbs real-time model to recognize the new ADC/DAC cards. Unfortunately, apparently due to changes to library parts made by Okutomi-san, neither the original model or Okutomi-san's new model can be successfully compiled and installed anymore! Debugging is ongoing. * Fabian finished the redesign of the EQ stops for the BS RM. Hirata-san will refine the 3D design and do drawings (estimated 1/2 day). * Fabian redesigned the cable clamp on top of the multi-purpose cube (on the RM) to avoid the need for clips. (These are too easily moved if the cables are moved during installation and removal of the safety bar between the RM and IM, which has to be done many times.) * Mark and Fabian reviewed the previous iJect payload parts order and flagged the items that need updating. * Mark worked on task lists and schedule. * Hirata-san finished the PR/SR mirror box modifications. * Hirata-san washed parts (screws and collets). |
=== Type B (Mark) === ==== Past week report ==== At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun): * We solved the problem with the OSEMs: cables had been plugged into the LED current monitor outputs, not the PD outputs. * We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power. * We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll. * We aligned the IM |

Past week report
At Kamioka (Mark, Ohishi-san, Fabian, Enzo, Hirata-san, Yoshioka-kun, Kozu-kun):
- We solved the problem with the OSEMs: cables had been plugged into the LED current monitor outputs, not the PD outputs.
- We solved a problem with the real-time model freezing which turned out to be the IO chassis having lost power.
- We took some mass off the IM to allow for the weight of the cables, and readjusted it in pitch and roll.
- We aligned the IM
