We should also have in-vac PD/QPDs, but they are not considered yet. For now, see JGW-D1402986.
For aLIGO, PD/QPDs below are in vacuum (see LIGO-T1000264).
- RF PDs for REFL, POP, AS
- RF QPDs for REFL, AS
- DC QPDs for MC2TRANS, POP, TRX, TRY, OMC (they don't have in air versions)
aLIGO TRX and TRY has high gain/low gain versions, but they are both in air.
