Two-dimensional Beam Profile Monitoring by Using a LYSO Crystal

摘要: We made a prototype two-dimensional proton beam profile monitoring system by using LYSO scintillation crystal attached to photomultiplier tube mounted on 2-dimensional scanner. measured the profiles of 45-MeV from MC-50 cyclotron at Korea Institute Radiological and Medical Science our system. energy flux simultaneously as device moved over area 180× 180 mm. To measure profile, we scanned −90 mm +90 along x-axis, well y-axis. also two diagonal lines point (−90, −90) (90, 90) −90). From these measurements, showed possibility being used device.
