A Comparison of Various Geometries of a Separated‐Sector Cyclotron

Quasi-continuously operating inductive accelerators

“…The difficulties encountered in the generation of the controlling field of a betatron with a constant controlling field were overcome in the course of those investigations and a simplified method of calculating and generating the field [6] wins developed. Experiments [9] were made and proved that it is possible to increase the controlling field at least up to 13 kOe without a substantial distortion of the field. The Laboratory of Problems of Novel Accelerators of the Physics Institute of the Academy of Sciences of the USSR used an electron ring phasotron with a maximum energy of 40 MeV in a series of experimental investigations and modeled systems and operating conditions of betatrons with a constant controlling field [7][8][9].…”

In particular, electron acceleration experiments were made with two injection methods: single, long-lasting injection and multiple injection of a group of short pulses with a high duty factor.…”
