Location of the servo components
Green lines represent cabling.
MC REFL optical table: PD, QPD
Around MCi, MCe chambers: OpLev
MC rack: I-Q demodulators, MC board, MC RTS computer, Coil drivers, Picomotor Drivers
Laser room: TTFSS box, AOM
Questions
Where to put TTFSS ? Do we need a rack inside the laser room ?
Demodulator
Assigned to Aso
Use 4ch I-Q demodulators for the moment. JGW-D1402413
Necessary channels: 1ch for Length PD, 8ch for WFS QPDs.

MC board
Assigned to Michimura and Nakano
- LIGOの回路図を見て，機能ブロック図を描く
→ LIGO-D1002416-v5(pole/zeroの位置は適宜調整されている可能性あり。参考: LIGO-D040180(回路図)、LIGO-E1200177(LIGOでの変更履歴))
- KAGRAで必要な修正点はあるか?
→ なさそう。
- AOMとの接続は単なるBNCケーブル?
→ SMBとSMCは必要(参照: JGW-T1402941)。
