SEI Status

SEI Status:

- Motion measured on ITMY (ISI and optical lever) using the LLO configuration was good again last night, so we duplicated this configuration to all the BSC-ISI units

- As we re-started the units, Jim found an oscilation in ITMX. He fixed it. It is not correlated with the new blend configuration. More details on that to follow.

- Hugh worked on the Guardian. It is now fully updated to account for the new config (decribed below). Thanks a lot to Jamie for the remote support. The Guardian is now fully updated and running.

- All the units are up and running. We leave the sensor correction OFF for the night.

 

Configuration in use:

- LLO blends installed everywhere (excact same filters copied/pasted from the filter text file)

- Stage 1 RZ off on all units

- Only Stage 1 X and Y isolated on Stage 2 (all units except the BS)

- Stage 2 damped only on the BS

- Sensor correction is off for the night
