Status report of the CERN light shining through the wall experiment with microwave axions and related aspects.

M. Betz, F. Caspers, M. Gasior & M. Thumm
One way to proof or exclude the existence of axion like particles is a microwave light shining through the wall experiment. In this publication we will emphasize on the engineering aspects of such a setup, currently under development at CERN. One critical point, to achieve meaningful results, is the electromagnetic shielding between axion-emitter and receiver cavity, which needs to be in the order of 300 dB to improve over existing experimental bounds. The RF leakage...
