Abstract

The production of radionuclides for medicine is an important field of application of modern cyclotrons for average energies accelerating light particles (protons and deuterons).

A series of compact cyclotrons, such as the CC-12, the CC-18/9 and the MCC-30/15 intended for the production of photon and positron emitters for SPECT and PET diagnostic centers has been designed and manufactured at the D.V. Efremov Scientific Research Institute of Electrophysical Apparatus. The cyclotrons ensure the acceleration of negative hydrogen and deuterium ions up to the following energies: the ÑÑ-12 – up to 12 MeV (hydrogen ions); the ÑÑ-18/9 – up to 18 MeV (hydrogen ions) and up to 9 MeV (deuterium ions); the ÌÑÑ-30/15 – variable energy: 18÷30 MeV (hydrogen ions) and 9÷15 MeV (deuterium ions). An external injection system is used in these cyclotrons; the beams of accelerated protons and deuterons are extracted by ion stripping on carbon foils.

The main advantage of the aforementioned cyclotrons is an easy access to the devices located inside vacuum chambers by moving apart a part of the magnet to a distance of up to 800 mm along the guides (the median plane of the cyclotron is located vertically).

Successful putting into operation of two CC-18/9 cyclotrons, one in Turky, Finland (2005) and the other in St.Petersburg (2006) allows us to realize a serial production of these accelerators intended for use at PET centers.

The parameters and characteristics of the main units of the aforementioned accelerators are given.

Abstract

The RF power supply system for exciting the resonance system of the ÌÑÑ-30/15 cyclotron is presented. The main parameters of the RF power supply system are: the 40.68 MHz operating frequency, the 25 kW output power (the continuous mode), the operating mode-continuous or pulse. The parameters of the RF power supply system, its schematic and characteristics of the main units are given.
