【 摘 要 】

Charged particle beam diagnostics is a key task in modern and future accelerator installations. The diagnostic tools are practically the «eyes» of the operators. Precision and resolution of the diagnostic equipment are crucial to define the performance. Transition and Diffraction Radiation (TR and DR) are widely used for electron beam parameter monitoring. However, the precision and resolution of those devices are determined by how well the production, transportation and detection of these phenomena are understood. This paper reports on initial simulations of TR and DR spatial characteristics. A good consistency with theory is demonstrated. Also, optical system alignment issues are discussed.
