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.
