* Overview * Current status of the KAGRA GND * Current status and requirements * Voltage monitor * Discussion item from AEL and DGS * GND map for DC power supply, racks, circuit and cables * Distinguish the cable for power and signal * DC and AC powers [[KAGRA/Subgroups/DGS/RTPC/Racklist|AC Power]] * Commets from Yamamoto-san [[KAGRA/Subgroups/PEM/GNDmeeting/200305/Yamat|memo]] * Discussion item from Laser * Where is the GND inside the PSL room * GND of the PSL table (Is there the ground loop? Why 120Hz was enhanced?) * GND of the IMC table * (Out of topics in this meeting?) Should we move the electronics to outside of the PSL room? (LIGO did) * Design and cabling at and around the IOO rack * Discussion item from interferometers * GND of the optical tables and PDs * Unexpected correlation for some PDs * Cabling * GND for instruments(cooler, oplev, etc) and interferometer * Chamber GND? * Others |
