Design Study on Standing-wave Linear Accelerator
A compact standing-wave linac has been designed using S-band microwaves for medical and industrial applications. It uses a bi-periodic structure with constant impedance. It consists of a buncher section with three-cells and on-axis coupled cavities with nine-cells. The total length is 740.0 mm including the electron gun. Using SUPERFISH, HFSS and PARMELA codes, it is capable to deliver 4.5 MeV ...
متن کاملThe Influence of High Frequency System of Standing Wave Electron Linear Accelerator on Beamoutput Properties
This article discusses high-frequency systems of standing wave linear electron accelerator. One of the drawbacks of standing wave accelerators is extended transient process in high-Q resonator sections, which leads to insufficient beam energy at initial stage of high frequency pulse and occurrence of medium energy spread of clusters. This spread can be eliminated by power supply of accelerator ...
متن کاملLaser Plasma Electron Linear Accelerator
The generation of an ultrashort relativistic electron bunch from a strong laser-plasma interaction have been studied by particle-in-cell simulations and observed experimentally. The electron beam was generated from the plasma created by focusing a Ti: sapphire 12 TW (tera watt) laser pulse at the edge of helium gas jet expanded into the vacuum from a pulsed supersonic nozzle. The laser pulse du...
متن کاملExperimental confirmation of transverse focusing and adiabatic damping in a standing wave linear accelerator
The measurement of the transverse phase-space map, or transport matrix, of a relativistic electron in a high-gradient, radio-frequency linear accelerator ~rf linac! at the UCLA photoinjector is reported. This matrix, which indicates the effects of acceleration ~adiabatic damping!, first-order transient focusing, and ponderomotive second-order focusing, is measured as a function of both rf field...
متن کاملDesign of Rf Feed System for Standing-wave Accelerator Structures
We are investigating a standing wave accelerator structure that uses a rf feed to each individual cell. This approach minimizes rf power flow and electromagnetic energy absorbed by an rf breakdown. The objective of this work is a robust high-gradient (above 100 MV/m) X-band accelerator structure.
