OMC meeting

Test on the AS table (Kokeyama)
- Measure the transmission outside
- Extract the actual beam, put it in the OMC
- Beam position check with single bounce
- OMC1 mirror inspection
- Check the mount size for modification
- Check the beam spots with a good alignment
PD holder modification (Somiya, Sato)
Mirror mount modification
- Order PZT now (Somiya)
- Machine the spare mount, glue the mirrors, and send to Kamioka
- Control the mount of glue (careful procedure the glueing)
Assembly procedure document and review
Cable on the beam path
- no idea
- Discuss in front of the OMC (Kokeyama, Aso)
700Hz damping structure (Somiya)
- LIGO parametric instability damper type thing (dynamic damper)
- Spring damping
- Damping metal M2052
Check the OMC suspension actuator in LIGO (Somiya)
Ghost beam OMC3 and 4, QPDs are not dump
- Order more beam dump (KG5) as spare (Somiya)
- Do we re-produce balanced masses?
AS table laser is 50mW
