Simulation and Optimization of Micromachined Vacuum Electron Gun

Computer Simulation of the Umer Electron Gun*

* Work supported by the U. S. Department of Energy at NRL under contracts DE-AI02-93ER40799 and DE-AI02-94ER54232, at U. Md. under DE-FG02-92ER54178 and DE-FG02-94ER40855, and at the HIFVNL under DE-AC03-76SF00098 and W-7405-Eng-48. Abstract An important feature of the UMER experimental program [1,2] is the continuing use of comparison between computer simulation and experimental measurement. T...

The Simulation and Analysis of Secindary Emission Microwave Electron Gun

Several new approaches for producing high-current, short-duration pulses of electron beams were reviewed briefly in this paper. The paper presents mainly the simulation and analysis of a secondary emission microwave electron gun. The movement of electron in microwave electric field was simulated and the self-bunching process of the secondary emission electrons in the gun was also proved. Some f...

Developments in the Electron Gun Simulation Program , EGUN

Technological progress in the performance of small computers has rapidly changed the demands on the software that is properly matched to the hardware. Table 1 shows running times on some PC-clones and workstations for the electron optics program EGN2 (1) running a simulation of a gun for an Electron Beani Ion Source (EBIS) (2). The speed increases shown in Table 1 have been accompanied by a red...

Simulation Study for Electron Gun Using Simion Computer Program

The manuscript reports the simulation of an electron gun with a view to optimizing the design of radio-frequency sources. The effects of eight parameters on the beam quality were studied and optimal choices were identified. It gives numerical beam qualities in common electrostatic triode gun, and the dependences on design parameters such as electrode geometries and bias voltages to these electr...
