Abstract: The new detection system for neutral particle analyser ISEP (isotope separator) of the thermonuclear reactor JET (England) was designed and developed. It was stipulated by the high (~ 10e11 s-1cm-2) n-g background in the analyser site. It is clear the device efficiency is determined by the detection system sensitivity to background radiation of the high temperature plasma. The results of the optimisation of the detection system to detect p, d, and t in the presence of the intensive n-g background are submitted. The thin (a few microns) CsI(Tl) scintillators are the sensitive element of such detectors were used. Their width was optimised for detection of the hydrogen isotopes with fixed energy. Uses of the standard amplitude analysis procedure for separation of signals from corpuscular particles and background radiation has allowed us essentially improve the signal-to-noise ratio of the neutral particle analyser ISEP.
