Summary of Continuous Wave Injection at bKAGRA phase1 operation
- Date : 2018/5/2 Night shift
- Worker : T.Yokozawa, A.Miyamoto, T.Sawada
- MICH LOCK flag
- K1:GRD-LSC_MICH_STATE_N (16Hz sampling)
- 1000 is operation mode
- K1:GRD-LSC_MICH_STATE_N (16Hz sampling)
- 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
- (1) K1:CAL-CS_CALHWI_CW_INJ_SW (16Hz sampling, on:1 off:0)
- Injection signal
- (4) K1:CAL-CS_CALHWI_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???)
The detail is summarized in (JGWDoc6924)
- 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_dat2.sh
- Prepare the dat files before injection, scp from other PC, using awgstream we injected signal.
- Injection waveforms generation
15 LIGO injection pulsars(LIGO O1 CWINJ)
- using lalapps_Makefakedta_v5
- 6 continuous sine
