  1. October 23, 2019 KAGRA ISCElectrical Components Layout Yuta Michimura Department of Physics, University of Tokyo 2017.9.11 Added PDs for RF AM generation

  2. Scope and Disclaimer • Draw rough layout of electrical components (RF distribution, PD/QPDs, servo boards) for KAGRA ISC • Cameras and picomotors are not included • Components for ISS, ALS, and OMC are very uncertain • “AS rack” is currently not on the rack list • Underlined ones are used also for iKAGRA • References: - JGW-D1402908 (IMC servo topology) - JGW-D1402984 (Cabling around PSL+IMC) - JGW-D1100425 (electronics racks layout) - JGW-D1402831 (what’s inside electronics racks) - JGW-T1402982 (list of ISC detection ports) - Wiki/OutputTables (list of output tables)
