Description
The NANOCD ALFA IZ experiment at ALFA plasma accelerator at the ELI Beamlines Facility in the Czech Republic, focused on the characterization and cross-calibration of electron beam charge diagnostics generated by the kHz L1-Allegra laser system. The primary objective was to establish reliable, non-invasive methods for electron beam charge estimation at such a high repetition level.
In this campaign, charge measurements obtained with a TurboICT detector (Bergoz Instrumentation) were cross-calibrated using Lanex Fast Back scintillation screens. Two Fast Lanex screens were positioned, respectively, before and after the vacuum-to-air transition window, while the TurboICT was installed downstream of the second Lanex screen. Several calibration configurations were investigated, including variations in camera acquisition time and Lanex camera gain settings, in order to evaluate systematic effects on the measured signal response and calibration stability.
The experiment aimed to improve the characterization of laser-plasma-accelerated electron beams and to support the development of reliable, non-invasive diagnostic methods. The obtained results also provide a basis for future comparison with conventional linac-based charge and dose calibration procedures.
