Note

Night work

Weekend

Report of work

• OMC: Beam spot on mirror moved. One (or more) of the mirrors seems to be misaligned. OMC will be pulled tomorrow.
• Y arm: 20dB suppression on LSC below 1Hz was seen on mass lock trial.
  • Opleve control was slightly changed from IM control to TM control.
  • High frequency is limited by noise. Needs high power coil driver modification.
• Type B: H2 on SR3 was noisy, but needs more time to investigate it.
• 80mHz peak was reduced by changing damping setting.
• RTPC for ASC and ALS were dead somehow.
