Transmission Monitor's Vibration Isolation Stage for X: preparation (TMS-VISX)

  • With a fixed stage.
  • TMS = BRT (beam reducing telescope) + GPT (Gouy phase telescope)

LVDTs

Be careful! The pin assignment in the Dsub shell or the signal phases would be different from the below for #1 and #2, as I needed to once detach the pins when I installed the LVDTs (Akutsu).

Polarity & Calibration Factor

  • V: postive means that the LVDT outputs positive counts when TMS-VIS moves upward, and so the calibration factors are set.
  • H: postive means that the LVDT outputs positive counts when TMS-VIS moves positive yaw (counter clock wise from top view), and so the calibration factors are set.
