Activities in this week

VIS/General

Summary: Ikeda-san worked following items;

(1) Measured the length of the network cable (15956) and now prepare to order the cables with DGS group.

(2) He got message from manufacturer that it is difficult to operate the picomotor for long time (more 24 hours). So he is now considering to request to AEL group to make the circuit box that turns power on and off with BIO signal like the stepper motor circuit. (15958)

(3) He made the new MEDM screen for stepper motor on MN stage which is developed by Nishimoto-kun. We can open the screen from [sitemap]/[STEPPING MOTOR]/[CRY_OVERVIEW] (15965).

VIS/PRM

Summary:

(1) Miyo fixed the swapped cabling on the BF-damper for PRM with Nakagaki-san, and after that, the noise coupling of the transfer function at higher frequency is decreased to the same behavior of other PR suspensions (15994).

(2) Ikeda-san touched the picomotor of PRM for his first operation (15957) before measure the calibration factor between picomotor and OSEM.

VIS/PR3

Summary: Ikeda-san tested the picomotor operation and measured rough calibration value for PR3-IM picomotor (15977). During the test for BF picomotor, it was stucked (15976). So we need open the top chamber to fix that.
