High 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...
متن کاملCurrent and prospective applications of metal ion-protein binding.
Since immobilized metal ion affinity chromatography (IMAC) was first introduced, several variants of this method and many other metal affinity-based techniques have been devised. IMAC quickly established itself as a highly reliable purification procedure, showing rapid expansion in the number of preparative and analytical applications while not remaining confined to protein separation. It was s...
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 کاملDesign of the new multilevel current source converter to grid connected applications
A novel current source multilevel inverter is introduced in this paper which is an appropriate alternative to be employed for low/medium power applications. the proposed converter is formed basic modules which paralleling these modules increse output current levels and improve quality of injected current to load or grid. in order to validate advantages of proposed converter versus the several m...
