Here is the current status of the aLIGO SEI work regarding the HAM chambers. Everything in red is a change from last week's status. Everything in green is available.
· HAM 1
o HEPI unlocked and running
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:
Unlocked 07/23
Offsets added to the actuation path to successfully reestablish alignment.
To be commissioned, Transfer functions available.
· HAM 3
o ISI: previously commissioned with HEPI locked (recent performance spectra - Calibrated), currently unlocked, in vacuum
Sensor correction installaton started.
New blend filters installed. aLigo Blend filters on all DOF but RX and RY. eLigo high roll off blend filters on RX and RY. Performance Spectra.
o HEPI:
Unlocked 07/23
Offsets added to the actuation path to successfully reestablish alignment.
To be commissioned
· HAM 4
