Description
With the upgrade of the CLARA facility, it is now eligible to deliver high-quality electron beams with energies of up to 250 MeV. We have performed various particle-in-cell (PIC) simulations using the CLARA beam parameters with idealized Gaussian distribution*. As the beam propagates through the beam-shaping and transport system, its phase-space distribution becomes more complex. In this work, PIC simulations are integrated into a start-to-end (S2E) simulation framework to address the issue. We use CLARA beam distribution from a beam tracking code as input for PIC simulations with FBPIC code, and simulate plasma wakefield acceleration with CLARA beam for a more realistic modeling of the experiment. The FBPIC simulation output can then be tracked through the CLARA dump line to simulate diagnostics signals such as screen images and to create a virtual experiment.
