EGUN is a world famous simulation tool, developed by Bill Herrmannsfeldt at Stanford Linear Accelerator Center (SLAC), for the numerical simulation of electron guns, including space charge, Child-Langmuir and Fowler-Nordheim starting routines and 3D relativistic trajectory calculation in 2D rectangular or axially symmetric electric and magnetic ...

Computer simulation plays an increasingly important role in the analysis and optimization of such electron guns. It provides both detailed insight into source physics as well as the basis for improved design of high performance electron guns. Due to …

2006年3月1日 · This paper introduces CST PARTICLE STUDIO TM, a specialist tool for the fast and accurate design and analysis of 3D electron guns. The new software is based on the multi-purpose electromagnetic solvers of the CST STUDIO family and incorporates their powerful modelling capabilities as well as successful algorithms of the MAFIA-TS simulators.

The electron gun plays an important role concerning klystron performance, especially for X-band klystrons with a small drift-tube diameter. This paper describes a new method for an electron-gun simulation by using MAGIC. MAGIC solves the Maxwell equations in the presence of charged particles on a time-domain. The

2023年12月28日 · In this paper, we present an accurate and fast method for analyzing the mechanical–electromagnetic characteristics of the electron gun. This method can simulate the electromagnetic characteristics of the electron gun after thermal deformation.

Electron Gun Simulation Workflow: Particle Tracking. Extract from CST Particle Studio® - Workflow and Solver Overview: Usually an electron gun is only one part of a complex device, for example a particle accelerator. The gun is used to create a collimated particle beam to be provided to other parts of the device.

Advanced models of electron emission and beam dynamics are developed. The thermal spread simulation of initial velocities of particles at a cathode is also added. Due to this the precision of high perveance gun evaluations is improved, and the scope of devices that can be simulated is essentially extended.

2007年7月30日 · In the paper, computer simulations are performed using Opera to evaluate and optimize electron guns. A normal sampling distance, a factor needed to be optimized, is discussed how to affect the results, as well as the simulation results are presented.

For simulation of electron beam guns laws and equa-tions describing the generation and emission of electrons from the cathode, the electric and magnetic elds and the trajectories of the electron beams are given in the following equations. The basic emission laws are used to describe the generation and emission of electrons. For
