Here is the current status of the aLIGO SEI work at Hanford. The main updates of this week are:

- ITMX, HAM2 and HAM3 have been tested (chambers are closed)

- HEPI generic and local models have been updated, installed and tested

 

·         BSC1 - ITMY

o    ISI + HEPI - Unlocked, Previously commissioned.

·         BSC2 - BS

o    ISI + HEPI - Unlocked, Previously commissioned.
 

·         BSC3 - ITMX
