DC type particle acceleration by an rf field

Charged-part,icle acceleration by an electric field of con-stant strengt,h corresponding to an E vector rotating per-pendicularly t,o a static magnet,ic guidance field is calcula-ted. DC type acceleration can be achieved; in a modified version very short high-intensity pulses can be produced. The acceleration principle is suitable for heavy particles at low and medium energies. High-current accelerators eco-nomic and reliable in use should be possible.
