Physical Review Accelerators and Beams, Vol 21, Iss 6, p 064201 (2018)
Expansion dynamics of single-species, non-neutral clouds, such as electron bunches used in ultrafast electron microscopy, show novel behavior due to high acceleration of particles in the cloud interior. This often leads to electron bunching and dynam

Linear and nonlinear resonant instabilities of charged-particle beams traveling in periodic quadrupole focusing channels are studied experimentally with a compact non-neutral plasma trap. The present experiments are based on the idea that the collect

The High Current Experiment at Lawrence Berkeley National Laboratory is part of the U.S. program to explore heavy-ion beam transport at a scale representative of the low-energy end of an induction linac driver for fusion energy production. The primar

High current and low emittance are principal requirements for heavy-ion injection into a linac driver for inertial fusion energy. An electrostatic quadrupole injector is capable of providing these high charge density and low emittance beams. We have

Stray electrons can arise in positive-ion accelerators for heavy-ion fusion or other applications as a result of ionization of ambient gas or gas released from walls due to halo-ion impact, or as a result of secondary-electron emission. We summarize

A multi-dimensional discrete-particle simulation code, WARP, and its application to heavy-ion fusion beams is described. The code's 3D package combines features of an accelerator code and a particle-in-cell plasma simulation, and can efficiently trac

We report the successful development and commissioning of new diagnostics for electron cloud and gas desorption studies on the High Current Experiment (HCX) at LBNL. These measure the time-dependent gas density in a 0.03 - 0.2 A 1 MeV K{sup +} ion be
