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.
· HAM 1
o HEPI unlocked and running
Ongoing 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), currently unlocked, in vacuum
o HEPI: to be commissioned, currently locked, models and electronics ready. Commissioning could start once HEPI is unlocked.
· 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 HEPI is unlocked.
· 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 ready. Temporary STS cables
Simulink Model was created.
Model is running, and MEDM screens are available in the Sitemap.
