THE DESIGN, CONSTRUCTION AND TESTING OPERATION OF PROTON CURRENT CIRCUIT ON ACCELERATOR HIC-KOTRON13

Abstract

The cyclotron HIC-KOTRON13 was installed and operated in Hanoi Irradiation Center in order to
produce radio-isotope
18
F. After that,
18
F is synchronized to
18
FDG, which is used to diagnoses early cancer
disease. This accelerator is the R/D product supported from Korea Institute of Radiological and Medical
Sciences (KIRAMS). It need to upgrade with the functions as the commercial PET Cyclotron. With PET-
Cyclotron, the beam current are measured at target, 4 collimators around target and at the beam
transmition line. With HIC-KOTRON13, the only beam current gauge on target is installed. The other
position such as collimators, beam line,.. beam current gauge are not installed. This report presents the
design, construction and testing operation of beam current proton gauge of HIC-KOTRON13. It operater
based on the plane FARADAY detector. Electronic scheme operates based on the beam current to voltage
converter (I-V converter). The data acquisition operates based on ADC converter and integrates beam
current on fixed time. The beam current gausses are installed at collimators around target with the
purpose to determine the beam position in the operation of HIC-KOTRON13.
