Laser wakefield acceleration is able to provide electron beams of GeV energy and continuously evolves toward higher energies. These beams have broad energy spectrum; hence, their measurements require diagnostics with wide energy acceptance. Here, we present a design of an electron spectrometer to characterize the beams in the energy range of 100 MeV–10 GeV, in a single shot. The design consists of 1-m long permanent dipole magnets and has a variable gap opening to accommodate different divergences and pointings of the electron beams. The design is backed by simulations, which are used to optimize the positions of imaging plates. The use of a collimator to improve the energy resolution in the case of large beam divergences and beam pointing is presented. We also present the Monte Carlo simulations to evaluate the signal to noise ratio, with and without a collimator. |
