A Digital Signal Recording Module for a Dust Hit Mass Spectrometer

Abstract

The hardware and software parts of the signal registration module for a dust-shock mass spectrometer are described. The module allows one to record the spectrum of an ion pulse with frequencies from 100 to 400 MHz; it uses two 14-bit analog-to-digital converters connected to a programmable logic integrated circuit. In this case, a temporary alternation of analog-to-digital converters is used. The test results of the dustproof mass spectrometer at a microparticle accelerator are given (noise level 0.6% of the amplitude of the measured signal, sampling frequency 200 MHz).
