“…Of particular relevance is the assessment of the role of the beam emittance for typical electron beams now available. Figure 5 3D PIC simulations using the quasistatic PIC code QUICKPIC [32] have been performed to examine in detail the spin precession and polarization dynamics in LWFA scenarios. To this purpose, a random sample of the externally injected electrons was tracked using a particletracking algorithm [36], which stored the trajectories and fields associated with the accelerated electron beam.…”

“…In order to identify the role of the beam emittance in more realistic scenarios, QUICKPIC [32] simulations using nonzero electron beam emittances were performed, using sim N ¼ 62:5 mm mrad (typical SLAC beam emittance) and keeping the rest of the laser, plasma, and beam parameters unchanged. For these values, Eq.…”

“…V the model is compared with numerical simulations in scenarios that go beyond the validity limits of the analytical theory. Two approaches were used: in the first approach, the prescribed electromagnetic fields and trajectories of electrons in the blowout regime are considered; the second approach uses the fully self-consistent electromagnetic fields and electron trajectories from 3D PIC simulations in QUICKPIC [32]. Finally, in Sec.…”

The acceleration of polarized electron beams in the blowout regime of plasma-based acceleration is explored. An analytical model for the spin precession of single beam electrons, and depolarization rates of zero emittance electron beams, is derived. The role of finite emittance is examined numerically by solving the equations for the spin precession with a spin tracking algorithm. The analytical model is in very good agreement with the results from 3D particle-in-cell simulations in the limits of validity of our theory. Our work shows that the beam depolarization is lower for high-energy accelerator stages, and that under the appropriate conditions, the depolarization associated with the acceleration of 100-500 GeV electrons can be kept below 0.1%-0.2%.

“…Using a fully self-consistent Particle-In-Cell (PIC) algorithm to simulate such a stage is still impractical with state of the art computing facilities. The use of reduced models [7,8,9] is therefore required to model acceleration of particle beams to these high energies as it can greatly reduce the required number of simulation hours. Here we use the fully self-consistent PIC algorithm, implemented in the code VORPAL [10], to simulate the evolution of an externally injected electron bunch over the accelerating stage by scaling the physical quantities with the plasma density.…”

Abstract. Laser plasma accelerators are able to produce high quality electron beams from 1 MeV to 1 GeV. The next generation of plasma accelerator experiments will likely use a multi-stage approach where a high quality electron bunch is first produced and then injected into an accelerating structure. In this paper we present scaled particle-in-cell simulations of a 10 GeV stage in the quasi-linear regime. We show that physical parameters can be scaled to be able to perform these simulations at reasonable computational cost. Beam loading properties and electron bunch energy gain are calculated. A range of parameter regimes are studied to optimize the quality of the electron bunch at the output of the stage.

“…While both plasma wavelength and total length of the plasma need to be increased as we wish to increase the beam energy gain, the laser wavelength stays fixed to 1 µm. Reduced models are used to overcome this issue, such as the Ponderomotive Guiding Center method [3,4,5,6,7] where the laser wavelength is not resolved and only the average ponderomotive force of the laser is modeled, and simulations in a boosted frame [8,9,10], where the simulation is done in a frame that moves at a relativistic velocity along with the laser pulse. Further challenge is to accurately simulate the electron beam properties as numerical noise accumulates in particle-in-cell simulations.…”

Abstract. Because of their ultra-high accelerating gradient, laser plasma based accelerators (LPA) are contemplated for the next generation of high-energy colliders and light sources. The upcoming BELLA project will explore acceleration of electron bunches to 10 GeV in a 1 meter long plasma, where a wakefield is driven by a PW-class laser. Particle-in-cell (PIC) simulations are used to design LPA stages relevant to the upcoming experiments. Simulations in a Lorentz boosted frame are used to gain significant speed up and to simulate the 10 GeV stages at full scale parameters, otherwise impractical. As criteria on energy spread and beam emittance become more stringent, PIC simulations become more challenging as high frequency noise artificially increases those quantities. To reduce numerical noise, we consider using a Poisson solve to calculate the beam self-fields. This method allows correct cancelation of the beam transverse self-forces and prevents artificial emittance growth for a matched beam in a linear focusing field.
