This article presents the results of developing an ionization profile monitor (IPM) designed for a wide beam, which collects ionization products from residual gas as a passing beam interacts with it. IPM consists of an extractor, a scanner, and two electrostatic analyzers. The monitor was tested using ion beams of 132Xe26+ with an energy of 1.2 MeV/amu and a residual gas pressure of 5 × 10−4 Pa. It was shown that the monitor allows for accurate measurement of wide beam profiles, achieving a resolution of 1.5 × 1.5 mm2 and a minimum sensitivity of 5∙103 particles/cm2‧s. The monitor is designed to ensure uniform beam distribution during transport to the target and to continuously monitor its changes. Two types of monitors have been developed: one for beam diameters of 45 mm for radiobiological research and one for 60 mm for testing radiation effects on electronic equipment.
