GEO600 Optical Layout 53 W 0.09 2.3 74 kw 3 5 kw 10 6 W
Tunable optical transfer function Signal Recycling provides an adjustable optical response (see talk by Stefan Hild) Lock acquistion at 2.5 khz, OPERATION NOW at 550 Hz.
Recent work on GEO600 Comissioning: improving detector sensitivity improving detector reliability improving detector characterization Joined S5 in overnight & weekend mode January 20th Joined S5 in 24/7 mode May 1st
Locking procedure (fully automated) PR error signal always available due to asymmetry in BS (~48/52) MI lock to dark fringe SR lock with three different signals in detuned state (~2kHz) Tuning to desired frequency (changing parameters in the process (see Stefans talk)) Switching MI lock to Single element diode Switching Servo parameters to lower noise & lower tolerance ones Ramping up power to final value In Total: ~ 3min
