Writing this alog to clarify some mistakes we have made regarding the naming of DCPDs. Jeff clarified to us on call this morning that the naming convention is A- photodiode on reflection, B- photodiode on transmission.

Therefore, here is the now corrected information about which high QE photodiodes are installed where, along with cabling and pin numbers:

OMCA (SN 103)

• DCPD B (TRANS)
  • DCPD: 1D-20
  • Housing: SN 10
  • cathode/anode/case wired to pins 1/2/6 of cable D2300118
• DCPD A (REFL)
  • DCPD: 1C-12
  • Housing: SN 06
  • cathode/anode/case wired to pins 4/5/9 of cable D2300118
• PZT cable D2300120

OMCB (SN 105)

• DCPD B (TRANS)
  • DCPD: 1C-14
  • Housing: SN 002
  • cathode/anode/case wired to pins 4/5/9 of cable D2300119
• DCPD A (REFL)
  • DCPD: 1C-10
  • Housing: SN 008
  • cathode/anode/case wired to pins 1/2/6 of cable D2300119
• PZT cable D2300121
