5 GEO600 Optical Layout 53 W kw 3 5 kw 10 6 W
6 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.
7 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
8 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
