E. Aprile et al., FIRST OBSERVATION OF THE SCINTILLATION LIGHT FROM SOLID XE, KR AND ARWITH A CSI PHOTOCATHODE, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 353(1-3), 1994, pp. 55-58
We have demonstrated that the scintillation light from solid Xe, Kr an
d Ar can be recorded by means of a CsI photocathode directly coupled w
ith the solid. The signal obtained from the CsI photocathode inside so
lid rare gases is 20-100% higher than that previously observed with Cs
I photocathodes inside the same liquids. This may open new application
s of solid rare gas scintillating detectors with such a readout.
