Abstract
This report documents the development of a current transformer system to measure pulsed ion beam currents at the LAMPF accelerator. Measured peak currents typically range from 100 nA to 30 mA with pulse widths varying from 30 ¿s to 1 ms. Signal conditioning of the peak current output provides an average current readout with a range of 1 nA to 2 mA, noise of approximately ±0.5 nA, and accuracy of ±0.1%. The system requires no operating adjustments and has proved stable and reliable during a year of operation.
