An Automatic Real Time Impedance Matching System for Use in an RF Electrostatics Accelerator Ion Source

Ion-source and LEBT Issues with the Front-End Systems for the Spallation Neutron Source*

The Front-End Systems (FES) of the Spallation Neutron Source (SNS) project are being built by Berkeley Lab and will deliver a pulsed 40-mA H ion beam at 2.5 MeV energy to the subsequent Drift-Tube Linac. The FES accelerator components comprise an rf driven, volume-production, cesium-enhanced, multi-cusp Ion Source; an electrostatic Low-Energy Beam Transport (LEBT) that includes provisions for t...

Compact Neutron Generator Development and Applications

The Plasma and Ion Source Technology Group at the Lawrence Berkeley National Laboratory has been engaging in the development of high yield compact neutron generators for the last ten years. Because neutrons in these generators are formed by using either D-D, T-T or DT fusion reaction, one can produce either mono-energetic (2.4 MeV or 14 MeV) or white neutrons. All the neutron generators being d...

Rf Acceleration of Ions Produced by Short Pulse Laser

An laser ion source which produces bunched ion beam is proposed to enhance an acceleration efficiency of ion accelerator front end with RFQ linac. To demonstrate a production of an initially bunched ion beam, H2 gas was ionized by short pulse laser in an RF electric field. As a result, ions captured by the RF field were observed by an ion probe.

Experimental Study of an Ion Cyclotron Resonance Accelerator

The Ion Cyclotron Resonance Accelerator (ICRA) uses a novel geometry which combines the radial confinement and azimuthal acceleration of cyclotrons together with the axial drift used in gyrotrons. Use of a common NbTi superconducting solenoid and an rf driven magnetron structure lead to a simple, lightweight, and compact machine that could be designed for portability. An ICRA designed to accele...
