Energy loss of intergalactic pair beams: Particle-in-Cell simulation
Aims. The change of the distribution function of electron-positron pair beams determines whether GeV photons can be produced as secondary radiation from TeV photons. We will discuss the instabilities driven by pair beams. Methods. The system of a thermal proton-electron plasma and the electron-positron beam is collision free. We have, therefore, used the Particle-in-Cell simulation approach. It...
متن کاملEnergy Management Simulation in a PEM Fuel Cell System
In this research the simulation of an air independent Proton Exchange Membrane Fuel Cell (PEMFC) propulsion system was taken into consideration. The system consists of several parts including PEM fuel cell stack, metal hydride and liquid oxygen (LOX) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. The heat recovery...

15 صفحه اولOptimal Transport of Low Energy Particle Beams*
*Supported by DOE and ONR The transport and matching problem for a low energy transport system is approached from a control theoretical viewpoint. We model the beam dynamics and transport section using the KV envelope equations. To this model we apply the principles of optimal control to formulate techniques which aid in the design of the transport and matching section. The techniques are appli...
