HughR, HugoP,
Here is the current status of the aLIGO SEI work at Hanford. Everything in red is a change from last status. Everything in green is available.
· BSC1 - ITMY
o ISI + HEPI - Unlocked, Previously commissioned. Performance Spectra
· BSC2 - BS
o ISI + HEPI - Unlocked, Previously commissioned. Performance Spectra
· BSC3 - ITMX
o ISI : Chamber-Side testing complete. Report validated. Ready for cartridge install.
o HEPI : Locked. Model is running. Electronics ready for turn on.
· BSC9 - ETMX
o ISI : Locked. Chamber-Side testing complete. Report Validated. Cartridge installed.
Needs balancing
o HEPI : Unlocked, ongoing initial alignment.
· BSC10 - ETMY
o ISI : Currently installed in BSC6. Will be pulled out and installed in BSC10. Payload (SUS) will be moved then. Electronics are disconnected
o HEPI : Unlocked.
HAM 1
o HEPI: Locked (09/18/13) and vented.
Low priority testing
One L4C needs to be replaced: H2
One actuator is weak: V4 It is 20% weaker than its counterparts. Likely clogged. May require replacement further down the line.
· HAM2
o ISI: previously commissioned with HEPI locked (recent performance spectra - not calibrated in higher frequencies), currently unlocked, in vacuum
o HEPI - IPS position loops and alignment offsets installed - recent performance spectra
Unlocked 07/23
· HAM 3
o ISI: previously commissioned with HEPI locked (recent performance spectra - Calibrated), currently unlocked, in vacuum
Sensor correction installaton started.
