Hirose-san, Ikeda > We placed the BS after the shutter and tried to turn the HWP remotely, but we couldn't. Specifically, we turned it at ‘K1:SYS-HWP_IFO_REFL_WFS_STEP_TOTAL_DEG’. The number on the MEDM screen"K1SYS-HWP_CALIB.abl" changed, but the IFO REFL WFS HWP on REFL table did not turn. I couldn't resolve it within today's work, HWP remains as is. The power before and after BS is as follows. (PDFfile) そのままで問題なく動作していた。 手順: 1. k1hwp4(IFO_REFL_WFS)の制御PCとの接続を確認 Ping: OK, ssh: OK, lsusb: OK 2. コネクターの接続 => 問題なし 3. HWPを見ながら10deg動かしてみた。 動作は正常、ただし指定した10degは回転しなかった。 => キャリブレーションは必要と考えられる。 結果: HWPは正常に動作することが確認できた。 --- Hirose-san, Ikeda > We placed the BS after the shutter and tried to turn the HWP remotely, but we couldn't.

Procedure:. 1. check the connection of k1hwp4 (IFO_REFL_WFS) with the control PC Ping: OK, ssh: OK, lsusb: OK 2. connectors. => no problem 3. ran 10deg while watching HWP. Operation normal, but did not rotate the specified 10 deg. => Calibration is considered necessary.
