Beam Dynamics Studies for a High Current Ion Injector *
Recent ion source developments resulted in the generation of high brilliance, high current beams of protons and light ions. After extraction and transport the beams with large internal space charge forces have to be captured, bunched and preaccelerated for the injection into the following driver part of a new generation of high intensity beam facilities for neutron sources, energy production, t...
متن کاملHigh-current, High-duty-factor Experiments with the H Ion Source for the Spallation Neutron Source
The ion source for the 1 MW Spallation Neutron Source (SNS) is required to provide 35 mA of H beam current at 6% duty factor (1 ms pulses at 60 Hz) with a normalized rms emittance less than 0.15 π mm mrad. The H beam will be accelerated to 65 keV and matched into a 2.5 MeV RFQ. The ion source is expected to ultimately produce 70 mA of H at 6% duty factor when the SNS is upgraded to 2 MW of powe...
متن کاملNew progress of high current gasdynamic ion source (invited).
The experimental and theoretical research carried out at the Institute of Applied Physics resulted in development of a new type of electron cyclotron resonance ion sources (ECRISs)-the gasdynamic ECRIS. The gasdynamic ECRIS features a confinement mechanism in a magnetic trap that is different from Geller's ECRIS confinement, i.e., the quasi-gasdynamic one similar to that in fusion mirror traps....
متن کاملAn ion source for molecular effusion studies
An ion source which utilizes a beam of monoenergetic electrons as the ionizing agent was designed and built for use in a 60° sector general utility mass spectrometer. The source was made to be used without a magnetic field to collimate the electron beam. The source is interchangeable with a surface ionization source that was already utilized in the mass spectrometer. Various operating character...
متن کاملHigh brightness inductively coupled plasma source for high current focused ion beam applications
A high brightness plasma ion source has been developed to address focused ion beam !FIB" applications not satisfied by the liquid metal ion source !LMIS" based FIB. The plasma FIB described here is capable of satisfying applications requiring high mill rates !!100 "m3/s" with non-gallium ions and has demonstrated imaging capabilities with sub100-nm resolution. The virtual source size, angular i...
