The Maryland Electron Ring for Investigating Space-charge Dominated Beams in a Circular Fodo System∗
The University of Maryland Electron Ring (UMER), currently under construction, has been designed to study the physics of space-charge dominated beams at extremely large values of the betatron tune shift which exceed those of existing strong-focusing synchrotrons and rings by more than an order of magnitude. In this paper, the unique design features of this research facility, the new beam physic...
متن کاملResistive-wall Instability Experiment in Space-charge Dominated Electron Beams
The resistive-wall instability of charged particle beams has been experimentally studied in space-charge dominated electron beams. The beam energy is in the range of 3 to 8.5 keV, the beam current is between 25 mA and 62 mA. In the experiment, electron beams produced from a thermionic cathode are passed through a 0.96 m long glass tube coated with a resistive material, and localized space-charg...
متن کاملTracking of Electron Beams with Numerically Determined Space Charge Forces
A tracking algorithm for the description of electron beams using grid-based space charge fields is compared to a method based on point-to-point calculations. The charged particles’ equations of motion are solved with a fifth-order embedded Runge-Kutta method using the concept of macroparticles. The space charge forces are determined in the bunch’s restframe with a multigrid-method [1].
متن کاملCollective Effects and Instabilities in Space Charge Dominated Beams*
This paper will illustrate the use of computer simulations to study collective beam dynamics in high intensity proton rings. More and more, computer codes are used to perform desktop experiments that provide the experimenter thorough control and visualization capabilities. In this role, the simulation code confirms and demonstrates the limits of theoretical and computational analysis, aids in t...
