J. Kissel, D. Tuyenbayev,
We turned on two calibration lines using ETMY coil drivers on stages L1 and L2. The SNRs of these lines are roughtly 1/3 of the regular calibration lines (regular cal. lines have SNR of ~100 with 10s FFT).
_FREQ (Hz) _CLKGAIN (ct)H1:SUS-ETMY_L1_CAL_LINE 33.7 60.0 O2-scheme synched oscillator for kappa_U
H1:SUS-ETMY_L2_CAL_LINE 34.7 27.0 O2-scheme synched oscillator for kappa_P
These lines will be used to better quantify calibration of the PUM and UIM actuators.
A related report: LHO alog 29291.
κU, κP and κT using these additional lines at ~6am on Wed., Oct. 12 are:
κU = 0.9828 - 0.0637i
κP = 0.9499 - 0.0380i
κT = 0.9784 - 0.0440i
These are preliminary values calculated manually for transfer functions taken at a selected time (no trends or averaging except for 10avg. in DTT), and the DARM model for ER9 (H1params_2016-07-01.conf). We will use SLM tool data to look at the parameter trends.
Greg M, Darkhan T,
We calculated kappa values using SLM data (10s FFTs) generated over 10 days between Oct 10 and Oct 21 with ER9 parameter file
'${CalSVN}/Runs/PreER9/H1/params/H1params_2016-07-01.conf'
The plots show raw (unaveraged) values. SNRs of the L1 and L2 lines (used for calculation of κU and κP respectively) were set to give approximately 1/3 SNR compared to the L3 line (with the ER9 noise floor).
The data was taken from an additional SLM tool instance which was setup by Greg to calculate 33.7 Hz, 34.7 Hz, 35.9 Hz and 36.7 Hz line FFTs.
