Operational Studies of the 10 keV Electron Storage Ring UMER
The University of Maryland Electron Ring (UMER) is now operational. UMER can operate with currents from 0.6 mA to 100 mA, ranging from the emittance dominated to the heavily space charge dominated reg...

Inthis paper, we discuss the parametric resonance model of halocreation, and compare it with self consistent simulation results. Inparticular, we employ two different initial distribution functions, and wefind agreement with the particle-core model, within the limitations ofthe latter. Furthermore, using a simple particle tracking algorithm, weare able to follow the trajectories of the halo particles,noting that a large number of them go through thecore and re-emerge later. ©2009 American Institute of Physics
