1 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK ALBERT-EINSTEIN-INSTITUT Karsten Kötter1 Detector Characterization of GEO600 4th Edoardo Amaldi Conference On Gravitational Waves UWA - Perth, Australia Karsten Kötter

2 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter2 Detector Characterization (1) First Phase: Improve Detector Performance identify noise sources track down transients Detector is a large and complex device data from many sensors have to be monitored (and recorded) at the same time detector data environmental data

3 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter3 Detector Characterization (2) Second Phase: create vetoes for h-channel external influences make data from h- channel invalid periods of invalid data have to be marked understand noise propagation in detector determine thresholds in environmental disturbances that affect h-channel

4 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter4 Available channels

5 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter5 environmental channels (1) already available sensors magnetic field seismic motion foundation suspension system power line indoor/outdoor temperature acoustics (air/tanks) wind speed/direction

6 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter6 environmental channels (2) planned air pressure vacuum pressure electric field

7 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter7 detector channels Mode Cleaner PDH error point visibility (reflected light) auto-alignment rotation tilt mirror positions

8 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter8 seismic noise spectrum

9 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter9 transient – seismic motion

10 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter10 transient - ModeCleaner control

11 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter11 coherence: seismic motion

12 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter12 transient - magnetic field

13 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter13 Detector signals during lightning

14 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter14 coherence: mag. field gradient

15 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter15 temperature fluctuations

16 MAX-PLANCK-INSTITUT FÜR GRAVITATIONSPHYSIK - ALBERT- EINSTEIN-INSTITUT Karsten Kötter16 Summary Detector characterization detector improvement h-channel vetoing DAQ system signals detector environment measurements seismic noise magnetic field temperature correlation
