Flat-Topping Magnet Current for the Berkeley Electron-Ring-Accelerator Experiment

The Physics Experiment for a Laser - driven Electron Accelerator

A physics experiment for laser-driven, electron acceleration in a structureloaded vacuum is being carried out at Stanford University. The experiment is to demonstrate the linear dependence of the electron energy gain on the laser field strength. The accelerator structure, made of dielectric, is semi-open, with dimensions a few thousand times the laser wavelength. The electrons traverse the axis...

Kinetic Stability Properties of an Intense Relativistic Electron Ring in a High-current Betatron Accelerator

Planar Permanent Magnet Multipoles For Particle Accelerator And Storage Ring Applications

In prior work a planar permanent magnet. (PM) configuration for generating an approxinlat~e quadrupole field distribut,ion in the vicinity of its symmetry axis was disclosed. In the present paper extensions of the inet,hod are considered for generat,ing sextupole and higher order multipole fields. The field distributions and strengt,hs are contrasted with idealized (azimuthally periodic) mulhip...

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...

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...
