North-Holland, Amsterdam RF AND SPACE-CHARGE EFFECTS IN LASER-DRIVEN RF ELECTRON GUNS
Laser-driven rf electron guns [1] are potential sources of high-current, low-emittance, short bunch-length electron beams, which are required for many advanced accelerator applications, such as free electron lasers and injectors for high-energy machines. In such guns the design of which was pioneered at Los Alamos National Laboratory [1] and is currently being developed at several other laborat...
متن کاملEarly transverse decoherence of bunches with space charge
The transverse decoherence of injected bunches is an important phenomenon in synchrotrons and storage rings. The initial stage of this process determines the transverse emittance blowup, which should be taken into account for the design of feedback systems, for example. The interplay of different high-intensity effects can strongly affect the initial decoherence stage. We present a model that e...
متن کامل3d Space Charge Calculations for Bunches in the Tracking Code Astra∗
Precise and fast 3D space charge calculations for bunches of charged particles are of growing importance in recent accelerator designs. One of the possible approaches is the particle-mesh method computing the potential of the bunch in the rest frame by means of Poisson’s equation. Fast methods for solving Poisson’s equation are the direct solution applying Fast Fourier Transformation (FFT) and ...
متن کاملThe Performance of 3d Space Charge Models for High Brightness Electron Bunches∗
Precise and fast 3D space charge calculations for high brightness, low emittance electron beams are of growing importance for the design of future accelerators and light sources. In this paper we investigate the performance of the 3D space charge models implemented in the tracking code Astra. These are the FFT-Poisson solver with the integrated Green’s function and iterative Poisson solvers fro...
متن کاملTESLA Report 2003-04 3D Space-charge model for GPT simulations of high-brightness electron bunches
Abstract. For the simulation of high-brightness electron bunches, a new 3D space-charge model is being implemented in the General Particle Tracer (GPT) code. It is based on a non-equidistant multigrid solver, allowing smooth transitions from a high to a low-aspect ratio bunch during a single run. The algorithm scales linearly in CPU time with the number of particles and the insensitivity to asp...
