Arc and Chicane Bunch Compression Schemes for Hard and Soft X-Ray Free Electron Laser Facilities: A Comparison
Adam Dixon, Peter Williams, Sara Thorin +4
X-ray free-electron laser (XFEL) facilities require progressive compression of electron bunches as they are accelerated from an injector to the undulators. This is necessary to ach…

First demonstration of coherent radiation imaging for bunch-by-bunch longitudinal compression monitoring
Joseph Wolfenden, Ana Guisao-Betancur, Carsten Welsch +5
Longitudinal bunch profile monitoring is a crucial diagnostic requirement in most accelerator facilities. This is particularly true in modern free-electron lasers and novel acceler…

Arc-Like Variable Bunch Compressors
Peter H. Williams, Gustavo Pérez-Segurana, Ian R. Bailey +3
Electron bunch compressors formed of achromat arcs have a natural advantage over the more commonly used chicane compressors in that linearisation of the longitudinal phase space is…
