14 MeV high intensity cyclotrons: Two projects in progress

Abstract

A 14 MeV high intensity compact cyclotron, CYCIAE-14, was built at China Institute of Atomic Energy (CIAE). In order to provide high quality proton beams for instant radiopharmaceutical distribution, and to produce a variety of radioactive ion beams taking use of the solid target, CYCIAE-14 adopts an injection system based on the external H- ion source, axial injection, and spiral inflector with a designed high beam intensity, while most PET cyclotrons adopt internal ion source. With the different using for the cyclotron, there are two projects. One project with 200μA/14 MeV can be used for isotope production of 11C, 15O, 13N and 18F. Another project with more than 400μA with 14 MeV can be used for more isotopes produced such as 64Cu, 124I and 99mTc. This paper will introduce the cyclotron of CYCIAE-14 with the two projects, and some experiments finished on the cyclotron will also be given in the paper, for example the 18F and 89Zr production, BNCT test.
