Activities in this week

VIS/General

Summary: Ikeda-san did following works

  • (1) a

  • 15737 We investigated the network connection. , satoru.ikeda

    • 15956 Comment, satoru.ikeda

  • 15958 About Picomotor's 24-hour operation , satoru.ikeda

  • 15965 Integration of Cryo Payload Phytron motor driver into MEDM , satoru.ikeda

  • 15983 I posted this by mistake. , satoru.ikeda

VIS/EY

Summary: Setup of the F2 stage in EY: installation of suspension wire, cabling, calibration of LVDT, check of FR range, tuning

  • 15950 Setup of F2 , ryutaro.takahashi

  • 15959 Connection between F3 and F2 , naohisa.satou

  • 15972 Cabling between F3 and F2 , naohisa.satou

  • 15982 Setup of F2 , ryutaro.takahashi

  • (!) Thursday 15993 Setup of F2 , ryutaro.takahashi

VIS/IX

Summary: Connection of the cryo-payload in IX, mounted the geophones onto the IP in IX, and compressed the F0 blades in IX.

  • 15981 Setup of pre-isolator , ryutaro.takahashi

VIS/MCE

  • 15987 MCe oplev , tomotada.akutsu

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.

  • 15957 Checking the operation of PRM's Picomotor PRM_BF and PRM_IM , satoru.ikeda

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.
