THE PRINCIPLES OF OPERATION, INSTALLATION AND DETERMINATION OF TECHNICAL PARAMETERS OF INTERNAL PIG ION SOURCE IN KOTRON-13CYCLOTRON

Abstract

Accelerators’ ion sources create electrostatic particles used in acceleration chamber. There are several types of ion sources applicable to accelerators with different purposes. The internal PIG ion source, thanks to its simple configuration, is largely used in many PET cyclotrons. The KOTRON-13 cyclotron installed at Hanoi Irradiation Center, Vietnam Atomic Energy Institute uses this ion source. The radiopharmaceutical ¹⁸FDG produced from KOTRON-13 center is used for PET/CT in early cancer diagnostic.

This report presents the principles of operation, installation and determination of technical parameters of KOTRON-13’s internal PIG ion source. The position of internal ion source, the ARC current of the ion source, the flow of hydrogen gas, etc. are determined by experiment with the purpose of achieving maximum current on target and optimalperformance for KOTRON13.
