Abstract

Accurate and reliable beam position measurements are required to commission and operate the DARHT II Accelerator. The beam position monitor (BPM) system developed for use on the DARHT accelerator consists of 31 electro-magnetic detector assemblies, a computer network based data acquisition system, and analysis software. During each "shot" each BPM uses arrays of b-dot detectors to intercept the electron beam\´s changing magnetic field. The detector outputs are individually recorded. Post shot analysis of the data provides the beam current and position information. This paper will provide an overview of the system and give details regarding its performance.
