Modeling Laser Wakefield Particle Accelerators with VORPAL: VORPAL is capable of simulating laser plasma accelerators (LPA) using several different models; full particle-in-cell (PIC), envelope, and fluid. The modular structure of VORPAL allows users to combine these models, for instance modeling the bulk plasma as a fluid, and the beam as PIC. Read more...

Modeling Particle Accelerators with VORPAL. Superconducting radio frequency: VORPAL uses a cut-cell algorithm to give more accurate fields than a stair-step approach used in many other particle-in-cell codes; Crab Cavities: VORPAL's self-consistent electromagnetic field algorithm allows for correct calculations of the time varying magnetic field which provides the rotation to the bunches; Electron Guns: VORPAL has unique capabilities combining particle and field interaction with complex geometries that allow the study of the effects of wake fields on multiple electron bunches; Wakefields: The modular structure of VORPAL allows users to combine models, for instance modeling bulk plasma as a fluid, a beam as PIC.

Modeling Vacuum Electronics with VORPAL. Klystron: a linear-beam vacuum tube used as an amplifier at microwave and radio frequencies; Cavity Magnetrons: high powered vacuum tube devices that generate microwaves; Multipacting: occurs when an oscillating field in a cavity or waveguide resonates with the periodic motion of electrons traveling between and colliding with the walls, leading to an exponential increase in secondary electrons; Collectors: Traveling-Wave-Tube efficiency depends strongly on the efficiency of the electron beam collector.
