HAM Status

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.
     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.

o   HEPI: Currently locked, to be commissioned
     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.

·         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 ready. Temporary STS cables
     Simulink Model was created.
     Model is running, and MEDM screens are available in the Sitemap.

o   HEPI: Currently locked, to be commissioned     
     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.

 

·         HAM 6

o   ISI: Chamber-Side testing complete
      getting ready for installation in chamber.

                            Electronics ready (Corner 2 CPS interface damaged by faulty cable, will be replaced today), 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.

 

o   HEPI: Currently locked, to be commissioned
     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.
