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.

  • 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(pole/zeroの位置は適宜修正必要)。

  • AOMとの接続は単なるBNCケーブル?

→ SMBとSMCは必要(参照: JGW-T1402941)。
