==== Past week report ==== At Kamioka (Mark, Ohishi-san, Enzo, Yoshioka-kun, Kozu-kun): * We finished installing the RM OSEMs and installed the new Type5-2.2 and 5-2.4 OSEM cables. * We hung the RM and set its pitch. * We doubled-checked the BS and RM pitch, tightened the clamps and removed the winch system. * We installed the bottom section of the security structure to protect the RM/BS. * We lifted the IM/RM/BS section and weighed it. It was about 1.25 kg too heavy for the new BF, so we improvised a lighter set of ballast masses. * We installed the section of the security structure up to the BF ring, and the BF crossbars and jacks of the assembly frame. * We brought in the new BF. * We installed the BF-IRM rods and IRM top plate. * We reinstalled the IM flags and other items that had been taken off to use the winch system. * We hooked the BF-IM rod (with hex cable clamp). (We did not unlock the BF keystone.) * We cabled and tested the IM-PIT, IM-ROL and IM-YAW picos and the BF FR stepper (but not, yet, the BF LVDT). |
==== Report for week of 1/29 ==== * Mark made two sets of in-air pico splitter cables (each with a triple for IM and a double for BF) for SR2 and SR3. * Fabian, Hirata-san and Kozu-kun worked on cabling and testing the IM pitch/roll/yaw picos, the BF FR and the BF LVDT. The LVDT connections were initially unreliable and Hirata-san had to redo the pins on the coil wires. * Fabian installed ballast masses in the BF. * Mark worked on schedule. * Mark did inventory of the stepper motor drivers (many were not accounted for on the wiki and/or JGWDoc and one is missing) and reserved two for SR3. * We emptied out the external cleanroom in preparation for installing SS sheet. |
