TI - Non-Destructive Monitoring of Electron Beam Micro-Bunching Periodicity J2 - Proc. of IBIC2020, Santos, Brazil, 14-18 September 2020 CY - Santos, Brazil T2 - International Beam Instrumentation Conference T3 - 9 LA - english AB - Electron beam microbunching can either occur naturally in high current accelerator facilities, or can be induced artificially for wide range of studies. Microbunching has applications in LINAC driven tunable sources of coherent radiation and wakefield acceleration. In all cases, an accurate, non-destructive monitoring of the beam microbunching is needed to validate theory, improve the accelerator and light source operations and understanding of the phenomenon observed. However, it is still a challenge to monitor the beam microbunching non-destructively and we discuss the possibility of measuring the femtosecond periodic microstructure of the beam without strong interference (i.e. in a non-destructive way) via analysis of the amplitude modulation of the coherent Smith-Purcell radiation (cSPr) signal generated by a partially or fully microbunched beam. The results of the numerical studies of the cSPr generated by the partially and fully microbunched beam and proof-of-principle experiments demonstrating the measurements of the distance between micro-bunches will be presented. The theoretical predictions are compared with the experimental data and the limitations are discussed. PB - JACoW Publishing CP - Geneva, Switzerland ER -
