Condensed xenon scintillators

Liquid and solid xenon were investigated as scintillator media for the detection of charge particles. The LET dependence of the integral light output was studied over a wide range of ionization densities using alpha and beta particles and heavy ions of 1.4 MeV/amu. For solid xenon, scintillation decay times were measured by the delayed single-photon method. For liquid xenon, a compact transportable detector unit coupled to a liquid-nitrogen cryostat was designed as a detector for medium-energy heavy ions. With an integrated solid-state detector this unit can be applied as detector telescope for particle identification.
