HIGH PRESSURE GAS SCINTILLATORS
Observations of scintillation pulse heights were made at pressures up to 75 atmospheres in xenon and argon, and in mixtures of nitrogen and xenon, nitrogen and argon, and neon and xenon. Diphenyl stilbene was used as a wavelength shifter. The most salient feature is that in all cases pulse height is approximately independent of pressure at pressures over a few atmospheres. The nitrogen-xenon and neon-xenon mixtures were used as neutron detectors via the N/sup 14/(n,p), N/sup 14/(n, alpha ), and Ne/sup 20/(n, alpha ) reactions. The resolutions achieved, particularly in nitrogen-xenon mixures (pulse height sometimes down to 1/40 of pure xenon), allowed a good estimate to be made of the number of phoons detected per unit energy loss in the scintillator.
