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...
متن کاملDesign study of a heavy ion fusion driver, HIBLIC
A heavy ion fusion (HIF) system, named HIBLIC (Heavy Ion Beam and Lithium Curtain) is conceptually designed. The driver system consists of RF linacs (RFQ linacs, IH linacs and Alvarez linacs), storage rings (one accumulator ring and three buncher rings) and beam transport lines with induction beam compressors. This accelerator complex provides 6 beams of 15 GeVPb ions to be focused simultaneous...
متن کاملPOSITIVE AND NEGATIVE ION MASS SPECTRA OF RING - SUBSTITUTED NITROBENZENES
The 70 ev positive and negative ion mass spectra of ring-substituted nitrobenzenes were studied. The influence of the substituent group on the fragmentation modes of the molecular ions is discussed. The effect of pressure in the formation of negative ions was also studied. As expected, the ratio of fragment ions to negative molecular ions decreased with increasing pressure in ion source.
متن کاملGas 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...
متن کاملHeavy Ion Fusion Sources*
In Heavy-Fusion and in other applications, there is a need for high brightness sources with both high current and low emittance. The traditional design with a single monolithic source, while very successful, has significant constraints on it when going to higher currents. With the Child-Langmuir current-density limit, geometric aberration limits, and voltage breakdown limits, the area of the so...
