Summary of Continuous Wave Injection at bKAGRA phase1 operation

  • Worker : T.Yokozawa, A.Miyamoto, T.Sawada
  • MICH LOCK flag
    • K1:GRD-LSC_LOCK_STATE_N (16Hz sampling)
      • 1000 is operation mode
  • 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 when evaluating the TM displacement
      • time delay between cal model and BS model (~61usec)
      • digital anti-imaging filter
      • time delay in the BS IOP(shared memory for DAC output) (~61usec)
      • time delay in the DAC output (There is unknown issue) (~60usec???)
      • analog anti-imaging filter
      • Coil driver(The transfer function is still investigated, with connection of coil)
      • Force to length transfer function(1/f^2 for higher frequency)
      • Actuator efficiency (Large measurement uncertainties due to fluctuation of optical gain)
  • Injection method
    • k1script:/users/yokozawa/inj_phase1/inj_dat.sh
    • k1script:/users/yokozawa/inj_phase1/inj_dat2.sh
      • Prepare the dat files before injection, scp from other PC, using awgstream we injected signal.
  • Injection waveforms
    • 15 LIGO injection pulsars(LIGO O1 CWINJ)

      • using lalapps_Makefakedta_v5
    • 6 continuous sine
    • Lists of continuous injection
