Abstract

A model-based feedback control system has been developed to correct beam displacement errors in the LLNL Advanced Test Accelerator (ATA) electron beam accelerator. The feedback control system drives an X/Y dipole steering system that has a 40 MHz bandwidth and can produce ±300 Gcm dipole fields. A simulator was used to develop the control algorithm and to quantify the expected performance in the presence of beam-position measurement noise and accelerator timing jitter. The major problem to date has been the protection of the amplifiers from the voltage that is inductively coupled to the steering bars by the beam.
