Summary of Continuous Wave Injection at bKAGRA phase1 operation

• Worker : T.Yokozawa, A.Miyamoto, T.Sawada
• Injection flag
  • (1) K1:CAL-CS_CALHWI_CW_INJ_SW (16Hz sampling, on:1 off:0)
    • Hardware injection switch of CW injection (used in injection flag)
  • (2) K1:CAL-CS_CALHWI_HWINJ_SW (16Hz sampling, on:1 off:0)
    • Hardware injection master switch (used in injection flag)
  • (3) K1:CAL-CS_CALHWI_(X/Y/BS)_GAIN (16Hz sampling)
    • Signal gain to X, Y, BS
• Injection signal
  • (4) K1:CAL-CS_CAL_HWI_HARDWARE_DQ (16kHz sampling)
  • Total amplitude of Hardware injection(CBC+CW+TEST)
• So, total amplitude of CW injection is
  • (1)*(2)*(3)*(4) [count]
  • But, we should apply transfer function between injection port and displacement of each test mass
