Secondary scintillation yield in pure krypton

The absolute secondary scintillation yield is of paramount importance for modelling dual-phase or high-pressure gas detectors, to be used in contemporary and future rare event detection experiments. In addition, the search neutrinoless double electron capture complements beta decay has been measured 124Xe several Dark Matter Double Beta operating at present. Krypton presents itself as an interesting candidate We have studied krypton yield, room temperature, a function electric field gap. A large area avalanche photodiode allow simultaneous pulses well direct interaction x-rays, latter being reference calculation number charge carriers produced by and, thus, determination photons impinging photodiode. An amplification parameter 113 per kV drifting threshold 2.7 Td (0.7 cm−1 bar−1 293 K) was obtained, good agreement with simulation data reported literature. On other hand, ionisation found around 13.5 (3.4 bar−1), less than what had obtained most recent work-package. about 80% 140% those xenon argon, respectively.
