Before placing installing the DC OMC and OMMT in the vacuum system we have to pre-align it on the flow benches in the clean room:

  1. use 500 mW (750?) NPRO, fiber coupled
  2. use auto-collimators and mirror flats to align and infinity
    • focus OMMT
  3. use few cm beam expanded fiber output to align OMMT to OMC
    • walk mirrors
  4. use OMC refl to maximize mode matching and walk in the OMMT
    • alignment
  5. align, mount, and register OMC DC PDs
  6. configure back propagating fiber and mode-match it
  7. Need to configure a temporary diode to measure the leakage
    • field from on of the OMC end mirrors.
