Abstract:
In this paper, the principle of adjusting the proton energy from the linear accelerator with energy adjusting cavities is proposed. The requirements to energy adjusting cavities for tuning the proton energy efficiently and continually are studied. The energy range adjustable and the energy spread are calculated for 35 MeV proton linac which is in the course of construction at the Institute of High Energy Physics, as an example. The energy spread as a function of electric parameters of energy adjusting cavities are also discussed. A specific and economical method to supply rf power to energy adjusting cavities is presented.
