Theory of Accelerated Orbits and Space Charge Effects in an AVF (Azimuthally Varying Field) Cyclotron

摘要

Two main subjects are studied in the report: (1) the motion of accelerated particles in an AVF cyclotron, and (2) the effect of space charge in an AVF cyclotron. The analytical models developed can be applied to a given cyclotron by adopting the relevant parameters. In the thesis, some calculations are made for the small 3 MeV Isochronous Low Energy Cyclotron (ILEC) which is presently under construction at the Eindhoven University. An important part of the study was started in relation with ILEC, and therefore some attention is given to the construction of this machine.
