Particle Beam Waist Location in Plasma Wakefield Acceleration
The role of beam waist location in interactions between a plasma and a particle beam is not yet fully understood. Nonlinear effects with the plasma make an analysis of such interactions difficult. Five simulations are presented in this report, with the waist location of a beam of ultra-relativistic electrons propagating through one meter of self-ionized lithium plasma. The simulation parameters...
متن کاملAutomatic Beam Path Analysis of Laser Wakefield Particle Acceleration Data
Numerical simulations of laser wakefield particle accelerators play a key role in the understanding of the complex acceleration process and in the design of expensive experimental facilities. As the size and complexity of simulation output grows, an increasingly acute challenge is the practical need for computational techniques that aid in scientific knowledge discovery. To that end, we present...
متن کاملTime-dependent Stochastic Particle Acceleration in Astrophysical Plasmas: Exact Solutions including Momentum-dependent Escape
Stochastic acceleration of charged particles due to interactions with magnetohydrodynamic (MHD) plasma waves is the dominant process leading to the formation of the high-energy electron and ion distributions in a variety of astrophysical systems. Collisions with the waves influence both the energization and the spatial transport of the particles, and therefore it is important to treat these two...
متن کاملParticle acceleration and magnetic dissipation in relativistic current sheet of pair plasmas
We study linear and non-linear development of relativistic and ultrarelativistic current sheets of pair (e±) plasmas with anti-parallel magnetic fields. Two types of two-dimensional problems are investigated by particle-in-cell (PIC) simulations. First, we present the development of relativistic magnetic reconnection, whose outflow speed is an order of the light speed c. It is demonstrated that...
متن کاملParticle Generation in Pulsed Plasmas
A new pulsed coaxial plasma generator (PCPG) has been developed in order to allow for investigating particle generation in the quench of a propagating jet. The related process provides an extremely transient environment which is characterised by initially high energy and charge densities, steep temperature gradients and short particle residence times. The combination of high quench rates and hi...
