Development of a Scintillation Screen Monitor for Transverse Ion Beam Profile Measurment at the Khima Project

The scintillation screen monitor measures transverse profile of ion beam in beam transport line. The Korea Heavy Ion Medical Accelerator Project (KHIMA) has developed a scintillation screen monitor in the high energy beam transport (HEBT) line. The images of each beam pulse were recorded by CCD camera and evaluated the beam properties by the LabVIEW-based in-house program in real time. We designed a scintillation screen monitor using phosphor screen, P43. In order to investigate the limits of scintillating screen during beam profile monitoring at low intensity, we designed a remote control device of iris for the incoming light adjustment to the CCD camera. In this paper, we present details of the image processing system using the LabVIEW and the beam profile measurement results from the in-beam test.
