Electron beam ion sources and traps „invited..
The electron beam method of stepwise ionization to highest charge states has found applications in electron beam ion sources ~EBISs! for accelerators and atomic physics collision experiments as well as in electron beam ion traps ~EBITs! for x-ray and mass spectroscopy. A dense and almost monoenergetic electron beam provides a unique tool for ionization, because radiative recombination by slow e...
متن کاملExcitons in electrostatic traps
We consider in-plane electrostatic traps for indirect excitons in coupled quantum wells, where the traps are formed by a laterally modulated gate voltage. An intrinsic obstacle for exciton confinement in electrostatic traps is an in-plane electric field that can lead to exciton dissociation. We propose a design to suppress the in-plane electric field and, at the same time, to effectively confin...
متن کاملExcitation of electrostatic ion-cyclotron waves by an ion beam in a two-ion component plasma
An ion beam propagating through a magnetized plasma cylinder containing electrons, light positive potassium ions K+ , and heavy positive cesium ions Cs+ drives electrostatic ion cyclotron EIC waves to instability via Cerenkov interaction. Two EIC wave modes are present, the K+ and Cs+ modes. The unstable wave frequencies and the growth rate of both the light positive ion and heavy positive ion ...
متن کاملA simple double-focusing electrostatic ion beam deflector.
We have developed an electrostatic, double-focusing 90 degrees deflector for fast ion beams consisting of concentric cylindrical plates of differing heights. In contrast to standard cylindrical deflectors, our design allows for focusing of an incoming parallel beam not only in the plane of deflection but also in the orthogonal direction. The optical properties of our design resemble those of a ...
متن کاملANALYTICAL STUDY OF STEEL I-BEAM WITH STEPPED FLANGES
This paper presents a parametric study of steel I- beam with stepped flanges by using finite element analysis. Stepped flange beam is used in structures to decrease the negative bending moments near interior supports that causes failure due to buckling. Steps in the cross section can be achieved by adding cover plates to the beam flanges, changing the size of the hot rolled section, or changing...
