Abstract :
A compact, low power (2 W) electronic system which delivers all the high voltages required for portable gas proportional scintillation counters and has an optically coupled amplification output stage is described in detail. Its measured integral linearity is better than 0.0175% (rms). X-ray spectra demonstrating the performance of system are presented
