| * Fabian, Mark, Yokogawa-kun and Kuwahara-kun did BS installation at Kamioka: * Calculated BS pitch correction ([[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=5630|JGW-T1605630]]) * Hung dummy optic and set pitch. * Prepared RM. * Placed vacuum feedthroughs on assembly frame and cleaned D-Sub cables. * Decided position of BS rack with Miyakawa-san. * Measured maraging rods. * Placed safety rails, rearranged floor panels, cleaned new floor panels, and otherwise improved safety. * Hirata-san: * Made new 3D models of the maraging rods for PRx and SRx * Made new collet design for PRx and SRx. * Made new IM flag design for PRx and SRx. * Washed lots of Type A BF parts and OSEM parts. * Measure some BF part dimensions. * Pre-assembled parts for BFs. * Type B ongoing issues * Longer term to-do list * Do Inventor assembly for SR2 in chamber and on assembly frame (Hirata) - NEARLY DONE. * Part "disk security" top has to be modified - screw positions do not match. * Write more of payload assembly procedure (Fabian) - ONGOING * Write more of BS Assembly Procedure [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=4235| E1504235]], [[https://onedrive.live.com/redir?resid=D5CCFA70A378E0D0!195&authkey=!AM_usynuo9QI57g&ithint=folder,webloc|E1504235 draft]] (Mark) - ONGOING * Lower breadboard installation to be incorporated into the procedure document. * Work on BS simulation (Fabian) * Do BS Simulink model (Mark, Kokeyama) * Do 2D drawings of SR2 parts (Hirata) * Redesign SRx IM wire clamps for larger prisms, remachined RMs * Order SRM/PRM parts (Hirata/Shoda) * Order SRx fasteners (Hirata) |
* Mark updated the BS circuit diagram [[http://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=3600|D1503600]]: * Added information on the binary IO. * Renamed channels to conform to Okutomi-kun's new scheme. * Made the ADC/DAC channel assignment consistent and more logical. * Updated the stepper motor sections with info about the new driver chassis. * Mark and Hirata-san worked on collecting parts and tools that will be needed for cabling of the BS next week. (11 special-purpose cables need to be made for the picos/steppers/OSEMs/LVDT on the RM/IRM/IM/BF and, time permitting, 2 more for the SF.) * Mark worked on schedule. * Mark updated the installation procedure with lessons learned from the last few weeks. * Mark downloaded Hirata-san's Inventor model of the BS in the tank and starting thinking about installation of the suspension and lower bread board. |
