Abstract

A new system for control of the x‐ray energy from a 25‐Mev betatron is described. Modifications in the method of energy control and orbit expansion lead to improved operation. Calibration of the energy scale is based on reaction thresholds for D(γ,n), Bi²⁰⁹(γ,n), Cu⁶³(γ,n), and the threshold for excitation of the 15.116‐Mev state in C¹². The resulting energy scale is linear with respect to electron momentum to better than ±20 kev.
