Covers various aspects of negative ion production in plasma sources, their extraction into particle beams and subsequent transport, neutralization and exploitation. This book is of interest to researchers in plasma physics, particle accelerators and fusion. require development of negative ion sources (up to ion energies of 1 or 2 MeV) with care-fully reduced beam divergence [1, 2]. A mul-tiphysics approach is requested for study-ing most of physical and engineering issues involved[3, 4], as described partly in this pa-per. Negative ions are separated by a mag-netic eld from the co-extracted electrons.
An rf‐plasma‐sputter type heavy negative‐ion source can deliver a few mA to 12 mA of dc negative‐ion currents such as boron, carbon, silicon, and copper negative‐ion beams. These negative‐ion currents are comparable with the positive‐ion currents for conventional high current positive‐ion implantation, and thus could be newly.

We developed novel methods for producing negative C60 ion beams at the accelerator facility Takasaki Ion Accelerators for Advanced Radiation Application (TIARA) to increase the current intensity of swift C60 ion beams accelerated to the MeV energy region using a tandem accelerator. We produced negative C60 ion beams with an intensity of µ;A, which is . Second International Symposium on Negative Ions, Beams and Sources: Takayama City, Japan, 16 - 19 November ; [NIBS] Subject .

Anne's College, Oxford, UK on the 12 th – 16 th September, The symposium is jointly organized by the Science and Technology Facilities Council (STFC) and the Culham Centre for Fusion Energy. A Negative Ion Cookbook BNL TVDG Page 5 of Negative Ion Source Some of the measurements reported here were made with a source of the type described by Middleton1) and shown in Figure 1 beams and sources book is commonly known as a high-intensity source).
However, most were made with a source in which a spherical one replaced the cylindrical ionizer and a. Production of intense, very bright, negative hydrogen, ion beams and conversion of a high energy negative beam into a neutral beam are described.
The ion source work has used a cesium charge exchange source that has produced negative hydrogen beams greater than or equal to 10 mA with a brightness of x 10 to the 9th power A/sq m - rad squared.
Articles are hosted by Taylor and Francis Online. Techniques for forming a beam of negative molecular ions by attaching electrons to molecular gases are discussed and a conceptual design for a quasi-continuous source is given.
September, 20th. Photogallery from the Symposium now available. The 6th International symposium NIBS'18 (Negative Ions, Beams and Sources) was held on September, and hosted by the Budker Institute of Nuclear Physics SB RAS and Novosibirsk State University. The symposium was focused on the various aspects of the production and use of negative ions.
1. Introduction. A negative ion source of an NBI for future tokamaks, not to mention the ITER NBI, is indispensable because the neutralization efficiency of a positive ion beam is negligible at the required beam ion sources have the advantages of simplicity, reliability, and maintenance-free long life time compared to filament-arc ion sources.

The alkali-metal group elements (Li, Na, K, Rb, Cs) and the Ca group metals have a strong electropositive character. Vapours of these elements can be used as a target to convert positive ions to negative ions (figure ).
This is done by passing the positive ion beam thorough a vapour in an oven. The 4th International Symposium on Negative Ions, Beams and Sources – NIBS – will be held at the town of Garching, which is near Munich, Germany, on October 6th - 10th, The symposium is organized by the Max-Planck-Institut für Plasmaphysik.
Summary of this volume: The 5th International Symposium on Negative Ions, Beams and Sources continues a series of events that began in Initially called the Symposium on Production and Neutralization of Negative Ions and Beams, it only covered accelerator and fusion applications.
The NIBS Award, donated by D-Pace Inc. is for outstanding recent contributions to the fields of: physics, theory, technology and/or applications of sources, low energy beam transport, or diagnostics of negative ions. The International Program Committee chooses the winning nomination and the award is announced at the conference banquet.

Negative Ions, Beams and Sources Welcome. The 3rd International Symposium on Negative Ions, Beams and Sources will be organized from 3rd to 7th of September in Jyväskylä, Finland.
The event is organized by the Department of Physics of the University of Jyväskylä. News. The registration has been closed. An ion beam is a type of charged particle beam consisting of beams have many uses in electronics manufacturing (principally ion implantation) and other industries.A variety of ion beam sources exists, some derived from the mercury vapor thrusters developed by NASA in the s.
The most common ion beams are of singly-charged ions. Neutral beam injection with the negative-ion based NBI system for JTU started in March The system is designed to deliver deuterium neutral beams of 10MW at keV for 10sec using one beamline with two large-size negative-ion sources.
In a preliminary negative ion source test conducted in ahead of beam injection into JTU, a. The report focuses specifically on surface-plasma-type ion sources, which were first developed in the USSR and which show great promise for creating beams of high intensity, high brightness, and low emittance.
Mechanisms for optimum negative ion beam transport are also discussed. The former is called the volume source and finds its major application in production of negative hydrogen ion beams for fusion and high energy accelerators.
The latter has been developed into the plasma surface conversion negative ion source, which finds a wide application and produces nearly every kind of negative ion.A negative oxygen ion source is under development to produce O− and O2− beams used for a secondary ion mass spectrometer at Institute of Modern Physics (IMP), and both filament and radio frequency.
Negative ion mode Mass spectrometry is the most comprehensive and versatile tool. Recent advances in negative ion mode mass spectrometry have improved sensitivity, identification and elucidation.
