New f2p filters were installed on ITMY this morning. The statistical error of the coil gain setttigs are about 0.6 % at high frequency.
NEXT : PRM, SRM, BS, ITMX and ETMX.
Pendulum mode = 0.988 Hz, Q = 1
C1:SUS-ITMY_ULCOIL_GAIN = 1.02482
C1:SUS-ITMY_URCOIL_GAIN = -1.06831
C1:SUS-ITMY_LLCOIL_GAIN = -0.996671
C1:SUS-ITMY_LRCOIL_GAIN = 0.91079
UL: fz = 1.014824 Hz, Q = 1.027150
UR: fz = 0.975038 Hz, Q = 0.98688
LL: fz = 1.000229 Hz, Q = 1.012378
LR: fz = 0.972688 Hz, Q = 0.946116
New f2p filters were installed on ETMY.
The coil imbalances are now about 0.8% at high frequency (i.e. above the resonant freq of the pendulum mode)
