An efficient high-voltage power supply for a photomultiplier tube

An adjustable power supply for a photomultiplier tube operating in the pulsed spectrometric mode with a wide range of linearity is described. The power consumed by the source is 50 mW. The output voltage is varied from 800 to 2000 V. The maximum ripple amplitude is 2.5 mV

An amplitude-channel hodoscope based on programmable logic integral circuits for the Baksan Underground Scintillation Telescope

A schematic diagram of a hodoscope with 3200 amplitude channels is described. The hodoscope is based on state-of-the-art programmable logic integral circuits (PLICs). Thanks to the use of PLICs, it is capable of measuring the lengths of input signals in each channel and monitoring their shape. In addition, the average time of data readout from the activated channels has been reduced and the maintenance of the hodoscope has been simplified. The hodoscope circuit may be easily adjusted by reconfiguring the PLIC components. The hodoscope is built to CAMAC standard
