Descrizione
Accurately measuring the energy of very high-energy electron (VHEE) beams is crucial if they are to be considered for applications. Laser-driven electrons are notoriously known for beam pointing and divergence variations from shot-to-shot. We have developed a spectrometer system that accurately measures the energy, by simultaneously correcting for pointing and charge. We conducted laser wakefield acceleration experiments resulting in electrons reaching a maximum energy at above 400 MeV, with peak at ~165 MeV peak and ~65% energy spread. Such spectra, although broad, can prove sufficient for Flash radiotherapy if energies below 100 MeV are filtered out.
