A pulsed sputter negative ion source

2014 A pulsed source for Cs-ions has been constructed as part of a sputter ion source in Hortig geometry. A beam of Cs-ions is extracted from a tungsten surface ionizer and bunched into pulses a few ns wide by a combination of velocity and path-of-flight modulation. It is expected that such a beam will produce intense pulses of negative ions having pulse widths in the ns range. REVUE DE PHYSIQU...

Modified extraction geometry in a radio-frequency ion source

2014 This paper is to show that a number of plausible arguments supporting the use of Bayly and Ward’s extraction geometry in radio-frequency ion source can be put forward. The ThonemannHarrison and the Schmidt-Eyrich version of this method have been compared in a series of measurements from the points of view of working parameters and beam characteristics. Current, gas supply rate, mass spectr...

Gas Flow Influence on Negative Hydrogen Ion Generation within the Microwave-driven Negative Ion Source*

H ion was generated through two processes within a volume Csfree source. The density of molecule hydrogen gas will impact on the electron temperature within the primary discharge chamber that will influence the population of vibrational excited H2. Within the extraction region, the interaction between molecule hydrogen and H ion will is cause the dissociation of negative ion. To better understa...

Uniform Negative Ion Beam Extraction in a Cesium-Seeded Large Negative Ion Source with a Tent Magnetic Filter

For improvement of spatial uniformity of negative ion beams, the external magnetic filter was replaced to a novel tent-shaped magnetic filter in the JAEA 10 ampere negative ion source. The tent filter geometry is based on new findings in surface production of negative ions in high electron temperature plasmas. In order to link the tent filter, the original line-cusp field configuration on the s...

Experimental Program for the Princeton Ion Source Test Facility

A 100 kV ion source test stand formerly operated at Lawrence Livermore National Laboratory (LLNL) has been relocated to Princeton Plasma Physics Laboratory (PPPL), where it is being installed and prepared for operation. A variety of topics relevant to ionbeam-driven high energy density physics and heavy ion fusion will be explored on this facility. The practicality of magnetic insulation to imp...
