Abstract: The single pulsed magnetic field is widely used in various high--energyaccelerators. From 1981 to 1983, the measurement of the kicker magnet's wascarried out in Hefei National Synchrotron Radiation Laboratory. This paper presentsthe principle and the method for measuring the waveform, the distribution and theamplitude of the single pulsed magnetic field. The elimination of the error in thedistribution measurement and the application of the microcomputer in themeasurement are discussed.
