英文原文：Low-cost programmable pulse generator for particle telescope calibrationAbstractIn this paper we present a new calibration system for particle telescopes including multi pulse generator and digital controller. The calibration system generates synchronized pulses of variable height for every detector channel on the telescope. The control system is based on a commercial microcontroller linked to a personal computer through an RS-232 bidirectional line. The aim of the device is to perform laboratory calibration of multi-detector telescopes prior to calibration at accelerator. This task includes evaluation of linearity and resolution of each detector channel, as well as coincidence logic. The heights of the pulses sent to the detectors are obtained by Monte Carlo simulation of telescope response to a particle flux of any desired geometry and composition. Elsevier Science B.V.

For solar and cosmic ray particle telescopes, this calibration is usually carried out in two steps: first, a calibration of each individual detector using radioactive sources and standard nuclear instrumentation (NIM or CAMAC modules),following by a final test of the whole telescope performed in a particle accelerator site. The success of calibration on accelerator requires that, prior to the experiences, all detectors and electronics parameter (polarization voltages, amplifier gains and shaping times, thresholds, etc.) have nearly definitive values. Here we propose a cheap and simple pre-calibration procedure ba...
