Introduction SpectraGAMMA III is a portable 1024-channel multichannel analyzer unit. It can be used either in standalone mode or connected to a notebook PC. SpectraGAMMA III is an extremely flexible and powerful tool, suitable for different kind of use, ranging from on site environmental radioactivity to laboratory spectroscopy and individual or group radiation protection. SpectraGAMMA III can mount either NaI(Tl) or solid state probes of different sizes, in order to give to users a most appropriate choice, according to their needs. The internal memory can to store thousands of measures and tenths of acquired spectra. The Li-Ion batteries, with virtually no self-discharge, allow the instrument to be always ready when needed, even after a long time of not working. Full graphic display and stand-alone spectrum analysis with isotope identification. Info are grouped by type, for an easier understanding. The possibility of managing more than one detector make it a valid instrument both for labor

l’acn S.r.l. Via XXV Aprile 9/13 20023 Cerro Maggiore-MI Tel. 0331 420303 General Description SpectraGAMMA II is a radiation spectrum analyzer able to manage up to 7 different kind of phototube detectors altogether, including the possibility to generate an internal HV between 300 V and 1000 V. The analog input signal is sent to a front-end Stretcher, a mini-board designed to sample and hold the PMT signal and to generate a trigger signal towards the mother-board. A 10 bit ADC samples the input signal with a maximum rate of about 50 KHz which is then stored after application of efficiency...
