Improvement on the accuracy of beam bugs in linear induction accelerator

In linear induction accelerator t he resistive wall monitors kown as “beam bugs” have been used as essential diagnostics of beam current and location. This paper presents a new method that can improve the accuracy of these beam bugs used for beam position measurements. With a fine beam simulation set, this method locates the beam position with an accuracy of 0.02mm and thus can scale the beam bugs very well. Experiment results prove that the precision of beam position measurements can reach submillimeter degree.
