|MOPMR010||The Development of Scintillating Screen Detector for Beam Monitoring at the KHIMA Project||244|
It is important to measure the beam propeties such as position, size and intensity, when we control the medical beam qualities, So we developed the scintillation screen monitor used for beam profile monitoring and it will be installed at High Energy Beam Transport(HEBT) section to measure the beam parameters. This system consists of a terbium-doped gadolinium oxysulfide(Gd2O2S:Tb) phosphor screen and high speed charge coupled device camera. The CCD camera has the maximum 90 frame rate and 659 X 494 pixel resolution. This Camera is mounted at distance of 260mm from the center of the scintillation screen and with the angle of 45 degree to the scintillation screen which is mounted at the angle of 45 degree to the beam axis. The image analysis program was written in National Instruments LabVIEW using IMAQ driver. To reduce the image processing time, we optimized the prcessing flow and used LabVIEW built-in function. To evaluate this system, we measured the beam size and center position of the beam at KIRAMS on 50MeV cyclotron. In this paper, we present the manufacture of beam profile system based on a scintillating screen monitor and the in-beam test results of it.
