· HAM 1
o HEPI unlocked and running
Ongoing commissioing
· HAM2
o ISI: previously commissioned with HEPI locked (recent performance spectra), currently unlocked, in vacuum
o HEPI: to be commissioned, currently locked, models and electronics ready. Commissioning could starts once the IMC locks again.
· HAM 3
o ISI: previously commissioned with HEPI locked (recent performance spectra), currently unlocked, in vacuum
o HEPI: To be commissioned, currently locked, model and electronics ready. Commissioning could start once the IMC locks again.
· HAM 4
o ISI: In chamber, Previously tested during assembly validation, currently locked, no suspension installed, in-vac cables not connected, chamber temporarily closed.
Electronics ready, in field cables ready, in-rack cables 90%
o HEPI: Currently locked, to be commissioned
Electronics ready, in field cables ready, in-rack cables 90%
· HAM 5
o ISI: In Chamber, Previously tested during assembly validation, currently locked, no suspension installed, in-vac cables not connected, chamber temporarily closed.
Electronics ready, in field cables ready, in-rack cables 90%
o HEPI: Currently locked, to be commissioned
Electronics ready, in field cables ready, in-rack cables 90%
· HAM 6
o ISI: in a container. Need to be retrofitted with aLIGO censors (GS13, CPS) and to receive a new set of Actuator Cables. Cables and inertial sensors will be tested prior to installation. All this will happen chamber-side prior to installation in chamber. Commissioning will follow.
Electronics and cables started, the rest is ordered
o HEPI: Currently locked, to be commissioned
Electronics ready, in-rack cables 90%Here is the current status of the aLIGO SEI work regarding the HAM chambers. Everything in bold is to be completed for HIFO-Y. Everything in red is a change from last week's status. Everything in green is available.
