Description
Advanced accelerating techniques are evolving rapidly, enabling high energetic electron beams with smaller footprint than ever before. While the accelerating structures shrink significantly, longitudinal diagnostic components with femtosecond resolution like transverse deflecting structures also demand a significant amount of space, are costly and require precise synchronisation of their power source with the arriving electron bunch.
The TWAC project () aims for a fully-integrated compact accelerator, delivering ultrashort bunches (~10s fs) at low charge and energy (10 pC, 10 MeV), requiring corresponding small footprint, cost-efficient longitudinal diagnostics. Here, dielectric loaded waveguides are utilised as passive streakers (*) in which the self-excited transverse wakefields are imposing a kick which varies along the intra-bunch longitudinal position. The new parameter regime for this method is explored step-by-step at the ARES linac, for which a novel forward propagation reconstruction algorithm has been developed, which is based on a waveguide mode expansion with more than 100 modes to properly model the excited wake.
Applicability to lower energetic beams (~10 MeV) as expected for the final TWAC parameters is outlined, enabling a compact current profile diagnostic for novel compact accelerators with potential for industrial use.
Funding Agency
The TWAC project is funded by the European Union‘s Horizon Europe research and innovation programme (EIC Pathfinder scheme) under grant agreement n. 101046504.
