Today's activities

Workers: Hasegawa, Akutsu

Replaced two wrong mirrors on the green periscope; see here.
- [WAS] two BB2-E03 (Thorlabs) -> [IS] two HM-2037-45 (CVI) ;both types were brought from NAOJ).
- The total power seems improved???

Realize why the best 3rd BRT lens for green's location is now there? It is inconsistent with Morozumi's calculation. Due to the improper mode match (the distance betwen the lenses there) in the input table near the PR2 chamber??
Measure the transmitting power
Measure the height with a laser leveler? -> On the optical table outside, it seems 1000(table)+ 180? =1180?? 20mm less than the nominal value 1200mm ...
Make a model to drive signals from the TMS
Check the response of the TMS by swinging BS, PR2, PR3... etc... with commissioning people
Endのend用のフランジとりつけ。たぶん最後のほうで。
そこのフランジにとりつける透過光用ビューポート。神岡にあるCat.B.
外側の光学定盤の上の取り回しを考えよ。
