Today's work plan: 2019/7/17 1PM - 2019/7/18 1PM

Commissioning leader: Aso (July 17th-19th)

Afternoon

  • ETMY HP coil driver check (Takahashi, Yamada)
    • Watchdog, Output resistance, Cable resistance, Take a picture of the PCB
  • Check the maximum current acceptable by the in-vac cable.
    • Calculate theoretical limit (Ushiba)
  • AS alignment (Kokeyama et al)
  • SR3 OSEM check (Fabian, Terrence)
  • Y-arm mass lock trial (SB, EY, MN, et al)
  • ISS work (Yoshioka, Nakano)

Evening

  • Y-arm mass lock trial (SB, EY, MN, et al)
  • Type-A guardian work on ETMX (Kokeyama)
  • DRMI investigation ? (SB, EY, MN, et al)
  • Found Y end coil needed more range, more drive for MN (dominate 10Hz sensing noise limited, cross over)

Note

  • DC feedback works perfect
  • Tcam alignment system is done (see from camera screen)
  • ALIGNED guardian on ETMX (test phase)

Morning

  • HP coil driver modification ? (Yamada, Fabian, Terrence)
