Study of Laser Injection of Electrons into Plasma Wakefields
A proposed laser-plasma based electron source [1] using laser triggered injection of electrons is examined. The source generates ultrashort electron bunches by dephasing background plasma electrons undergoing fluid oscillations in a plasma wake. The plasma electrons are dephased by colliding two counter-propagating laser pulses. Laser intensity thresholds for trapping and optimal wake phase for...
متن کاملOPTICAL BUNCHING OF RELATIVISTIC ELECTRONS FOR INJECTION INTO A GeV PLASMA BEATWAVE ACCELERATOR
A proposed GeV plasma beatwave accelerator (PBWA) requires a high power 1 pm laser running on two frequencies. The vacuum interaction between such a laser and a relativistic electron beam is one mechanism whereby the electrons can be bunched such that when injected into the PBWA they occupy only small regions of phase situated at the peaks of the accelerating field. This is exactly what is requ...
متن کاملNumerical Calculation of Small-angle Collimator Wakefields for Short Bunches
Collimators are used to eliminate halo particles from the beam. To relax the wakefield effects a gradual transition from a large to a small aperture is used. However, the existing computer codes face severe problems for long tapered transitions. Two main sources of the problems are the grid dispersion and the staircase geometry approximation. Using recently developed time domain numerical appro...
متن کاملAn investigation into finding the optimum combination for dental restorations
The aim of the study was to find the optimum combination of materials and thicknesses to provide a tough, damage resistant multi-layer system with numerical methods to restore the damaged teeth. Extended Finite Element Method (XFEM) was used to assess the critical loads for the onset of damage modes such as radial cracks and plastic deformation in dental prostheses, which consist of a brittle o...
متن کاملLaser injection of ultrashort electron pulses into Wakefield plasma waves.
A novel laser-plasma-based source of relativistic electrons is described. It involves a combination of orthogonally directed laser beams, which are focused in a plasma. One beam excites a wakefield electron plasma wave. Another locally alters the trajectory of some of the electrons in such a way that they can be accelerated and trapped by the wave. With currently available table-top terawatt la...
