Today's activities
Workers: Akutsu, Nagano, K. Tanaka
BRT part
There were some homeworks left from the last March; see here.
Optics name (old -> New) |
Type of the optics |
The holder |
Note |
1st steering mirror -> STM3 |
Newly opened "CVI HM-2037-45" |
Polaris-K2S1 + washed but not vented M4 screw + ME-KAGRA-1704107-A-DWG |
I determied to leave the M4 screw without a vent hole, as there is a groove on the pedestal. The outer diameter of the optics was wiped to remove the pencil memo. The original one (TFVMQ-50.8C10-20-W1D-532/1064-ARS-30/40D) was stocked in the desiccator as of 20190205 |
Harmonic BS -> HBS |
HBSY21 |
Polaris-K2S1 + washed M4 screw + OptoSigma VRO-12-100 + VRS-12-100 + VBSP-40100 |
|
2nd steering mirror -> GST0 |
Newly opened "TFMQSP-50.8C10-20-532/1064-0/26D" |
Polaris-K2S1 + washed but not vented M4 screw + ME-KAGRA-1704107-A-DWG |
