The article describes circuitry for the energy control of the 31-Mev Brown-Boveri type betatron and gives the results of the energy calibration. Except supplementary circuits required for the above type betatrons, the common technique is used: the electron orbit is expamded at a given value of the magnetic flux, defining the electron energy. A better measuring of the flux is achieved by the use of an electronic voltage integrator. The arramgement enables a stabilization of about plus or minus 5 kev at 17 Mev for rather wide fluctuations of the magnet supply frequency and voltage. The energy calibratlon performed with thresholds and breaks in the excitation curves for ( gamma ,n) reactions in copper, oxygen and carbon shows excellent linearity of the relationship between the measured flux and the maximum energy of the x-ray spectrum. The positions of the breaks in the excitation curves found in this work agree very well with the published results. (auth)
