RF synchronized short pulse laser ion source [PDF]
Review of Scientific Instruments, 2015 A laser ion source that produces shortly bunched ion beam is proposed. In this ion source, ions are extracted immediately after the generation of laser plasma by an ultra-short pulse laser before its diffusion. The ions can be injected into radio frequency (RF) accelerating bucket of a subsequent accelerator.

RF Plasma source for a Heavy Ion Fusion injector [PDF]
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005 Abstract We are developing high-current ion sources for Heavy Ion Fusion (HIF) applications. Our proposed RF plasma source starts with an array of high current density mini-beamlets (of a few milliampere each at ∼100 mA/cm 2 ) that are kept separated from each other within a set of acceleration grids. After they have gained sufficient kinetic energy (
