Description

Conventional methods for measuring lower-energy particle beams (<several MeV), such as Faraday cups, moving wire scanners, and scintillators, are invasive and become impractical for higher-energy beams that exceed material tolerances. Current techniques for detecting beam drift often rely on spill radiation monitoring or beam position devices with off-axis electrodes, which can produce unwanted secondary particles. This study investigates a non-invasive X-ray inspection technique for beam characterization. Through simulations, we examine optimal X-ray energies, detector-beam configurations, scattering mechanisms, and profile reconstruction methods. The results demonstrate the feasibility of real-time beam monitoring without interfering with the primary beam path, offering significant benefits for high-energy physics experiments where maintaining beam integrity is essential.
