  • Apparent bi-stability of OpLev -> Replaced the satellite box -> Gone

  • Glitches -> Looks like the same problem as ETMY: DAC output goes to zero

* PCal: Binhua

• Aligned the beam within the PCal module

* ETMX camera: Yokozawa

• Ready but not installed

* TMS: no one to report

Report of work (*:responsible person)

• ETMX: *Takahashi, Ishizaki, Sato, Okutomi, Tomaru, Takahashi, Ushiba, Miyamoto, Enomoto, Nagano
  • Mirror will be aligned with beam today to REFL. But IR and green are not overlapped well.
  • Oplev is placed but not calibrated.
  • LVDT of BF seems to be something wrong. It could be satellite box.
• BS: *Enomoto, Enzo
  • Hightower coil driver and satellite box was replaced. Satellite box was something wrong. Oplev jump disappeared. But still glitch remains.
  • Hyper threading should be off.
• BRT: Nagano
  • TMS was seen and aligned to QPD.

Work plan (*:responsible person)

• ETMX: *Ushiba, Takahashi
  • Beam will be aligned more precisely with aligned IR.
• CAL: *Yamamoto
  • CAL model is tested using iMC.
• Camera: Yokozawa
  • EX camera takes every one hour. It is necessary 1 sec picture in the weekend.
