The FLASHForward Experiment at DESY | |
|
||
|
The FLASHForward experiment at DESY is a beamline built for electron-beam-driven plasma-wakefield acceleration. The drive beams, supplied by the linac of the free-electron laser FLASH, have energies of up to 1.40 GeV, a charge of up to 1 nC, emittance of a few mm mrad, a pulse duration down to 50 fs, and can be supplied at up to MHz repetition rates. In the future, FLASHForward aims to operate as a beam-quality-preserving, high efficiency, high-average-power plasma-based energy booster for FLASH. To achieve this, during its first data-taking period (2018-2021) novel techniques were developed to enable high-quality plasma wakefield acceleration at >GV/m accelerating gradients*. Further, the upper limits of the achievable repetition rate of plasma-based accelerators were explored for the first time with a view to demonstrating high-average-power (>kW) operation**. We report on recent experimental highlights and future plans for the facility.
