Description
The Any Light Particle Search ALPS II is a light-shining-through-a-wall (LSW) experiment
to investigate the existence of axions and axion-like-particles (ALPs) in the sub-meV mass range. The existence of these particles is motivated by multiple quarters, from QCD to stellar physics. ALPS II aims to convert 1064 nm photons into axions or ALPs aided by the presence of a magnetic field, in an optical cavity. After passing through a light-tight barrier, these particles reconvert to photons in another optical cavity in a magnetic field, before subsequent detection. The expected signal amounts to about one 1064 nm photon per day, necessitating a detector capable of observing this low regenerated photon rate
