This study aimed to develop a scintillation screen monitor
for high-current ion beam profiling. It was observed that the
conventional scintillation screen is unable to meet the requirements
of medium- and high-power accelerators due to the beam damaging the
screen and preventing it from functioning properly. Consequently, a
water-cooled tantalum-copper composite plate was adopted as the
target head and coated with potassium bromide powder. The
scintillating screen monitor employs the direct intercept method to
observe the beam profile and position recorded by a CCD camera. A
water-cooled beam profile monitoring system was manufactured and
subjected to preliminary experimental tests on an electron
accelerator. The results indicate that the screen monitor exhibits
good luminescence, and high resolution, and is capable of
effectively evaluating the beam position and profile.
