A variable time-resolution MCS for kinetic studies

Abstract

The design and operation of an inexpensive multichannel scaler (MCS) having an adjustable time resolution between 100 ns/channel and 12.8 mu s/channel is described. The device is installed in one of the peripheral expansion slots of a microcomputer and utilises a total of 2048 channels. Software control provided by a user interface program allows convenient device configuration and data manipulation, display and storage. Two applications are discussed.
