Jenne stepped down the ITM ring heaters in common today, and Keita okayed some commissioning time, so I checked on the DARM plant. We are still running with pro-spring detuning. From the measurement the MCMC gave the following fit: Gain = 3.15e+06 cts/m Pole = 428 Hz Delay = 5.64e-05 s Spring Freq = -3.03 Hz Q = 349 This is an apparent reduction in the DARM optical gain as reported on March 20th. From March 20th, The DARM optical gain goes down, the DARM pole increased, the spring frequency went from -4 Hz to -3 Hz. The only thing about the DARM plant which has changed is the ITM ring heaters temps going down, as far as I know.
