The Electron-Ring Accelerator

Electron cloud dynamics in the Cornell Electron Storage Ring Test Accelerator wiggler

The interference of stray electrons (also called ‘‘electron clouds’’) with accelerator beams is important in modern intense-beam accelerators, especially those with beams of positive charge. In magnetic wigglers, used, for instance, for transverse emittance damping, the intense synchrotron radiation produced by the beam can generate an electron cloud of relatively high density. In this paper th...

Laser Electron Accelerator

An intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force. Electrons trapped in the wake can be accelerated to high energy. Existing glass lasers of power density lotsW/cm shone on plasmas of densities 10 8 cm can yield gigaelectronvolts of electron energy per centimeter of acceleration distance. This acceleration mechanism...

Commissioning the First Mobile Dedicated Accelerator for Intraoperative Electron Radiotherapy in Iran

Introduction: Intraoperative radiotherapy is a radiotherapy technique in which a high single fraction of radiation dose is delivered to the patient after surgery and Concurrent with anesthesia time. The most frequent method for IORT implementation is Intraoperative electron radiotherapy (IOERT), in which, some dedicated and high dose per pulse electron accelerators are employe...

Laser 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...
