This paper describes the successful engineering developments to mitigate this. The raft of measures included ‘skyhook¿ damping i.e. active damping using geophone velocity feedback, novel 2 stage passive vibration isolation and fundamental research into acoustic coupling of air conditioning noise. The new systems have been installed, the final performance tested and the optics scientists have been able to continue their sensitive measurements.
