AI Article Synopsis
- A new beam-position and profile monitor for synchrotron X-ray beamlines uses scattered radiation from a thin polyimide foil.
- This paper introduces a ray-trace model that helps calculate how changes in the device's geometry affect its performance for a specific beam size.
- The model's predictions on beam position sensitivity, profile shape, and intensity are validated against experimental data from the European Synchrotron Radiation Facility.
Article Abstract
A two-dimensional beam-position and profile monitor for synchrotron X-ray beamlines was recently presented that was based on the principle of collection of scattered radiation from a thin polyimide foil. This paper presents a simple ray-trace model of the device, which can be used as a tool to calculate its response to changes in various device geometrical properties for a given beam size. The tool provides a quick way of predicting positional sensitivity, beam profile shape and intensity distribution. The theoretically obtained beam images are compared with data obtained from experiments carried out at the European Synchrotron Radiation Facility.
