FLASHForward is a beam-driven plasma wakefield accelerator located at DESY in Hamburg. Within the FLASHForward project, a laser-driven wakefield setup is used as testbed for the characterisation and development of diagnostics for plasma wakefield accelerators. These include different non-invasive charge diagnostics that are also tested for their usability in EMP noisy plasma environment....
Novel accelerator techniques such as dielectric laser acceleration (DLA) will be studied at the SINBAD facility (DESY Hamburg) using the ARES linac. Due to the low charge of the accelerated beams, charge densities below 1 aC per square micron are expected at the spectrometer screen, which are challenging to measure with conventional techniques used in multi-pC accelerators. Therefore, a...
We report on two years’ studies of beam-based coherent radiation performed at the CLEAR facility of CERN.
Coherent Cherenkov-diffraction radiation has been exploited for the design of novel beam instrumentation both for beam position and bunch length monitoring.
With the aim to reach high-intensity THz generation in view of THz-acceleration experiments, different mechanisms have been explored...
Understanding of both driver and witness bunches in beam-driven plasma-wakefield acceleration (PWFA) experiments is critical in order to gain a deeper insight into what happens behind the scenes of the plasma cell i.e. validation of theory and control over the acceleration processes. However, witness bunches with lengths on the order of several femtoseconds are difficult to temporally resolve...
