Optical transition radiation (OTR) has become a commonly used method for 2D beam imaging measurements. In the Accelerator Test Facility 2 (ATF2) at KEK, sizes smaller than OTR point spread function have been measured. Simulations of system performed using ZEMAX software to study effects optical errors such as aberrations, diffraction, and misalignments components. This paper presents comparison simulations with experimental data obtained ATF2. It shows how quantification control impacts on...

Plasma accelerators present one of the most suitable candidates for development more compact particle acceleration technologies, yet they still lag behind radiofrequency (RF)-based devices when it comes to beam quality, control, stability and power efficiency. The Horizon 2020-funded project EuPRAXIA ("European Research Accelerator with eXcellence In Applications") aims overcome first three these hurdles by developing a conceptual design international user facility based on plasma...
