Pyroelectric deflector of charged particle beam
A new type deflector of a charged particle beam based on pyroelectric crystals is proposed and demonstrated experimentally. The transverse electric field arises in the gap between two pyroelectric crystals in vacuum because of the pyroelectric effect appearing when a temperature gradient is applied to both crystals. In a proof-of-principle experiment, we demonstrated deflection of a low-energy ...
متن کاملQuantum theory of charged-particle beam optics
Charged-particle beam optics, or the theory of transport of charged-particle beams through electromagnetic systems, is traditionally dealt with using classical mechanics. Though the classical treatment has been very successful, in designing and working of numerous charged-particle optical devices, it is natural to look for a deeper understanding based on the quantum theory, since any system is ...
متن کاملCharged-Particle Transport in anisotropic magnetic Turbulence
Turbulence with an associated turbulent magnetic field is common in astrophysical environments. The determination of the transport of charged particles both parallel and perpendicular to the mean magnetic field is of considerable interest. Quasi-linear analysis or direct numerical simulation can be used to find the effects of the turbulent magnetic field on the transport of charged particles. A...
متن کاملOn the accuracy of the Fokker-Planck and Fermi pencil beam equations for charged particle transport.
Electron beam dose calculations are often based on pencil beam formulas such as the Fermi-Eyges formula. The Fermi-Eyges formula gives an exact solution of the Fermi equation. The Fermi equation can be derived from a more fundamental mathematical model, the linear Boltzmann equation, in two steps. First, the linear Boltzmann equation is approximated by the Fokker-Planck equation. Second, the Fo...
متن کاملWigner Transform and Quantum-like Corrections for Charged-particle Beam Transport
It is well known that thermal spreading among the electronic rays is a typical effect that takes place in charged-particle beam transport in free space. In 2-D case, we denote with x and z the transverse and beam propagation coordinates, respectively. By using a statistical description, one can introduce with the second-order moments: σx(z) = 〈x 〉, σp(z) = 〈p 〉, and σxp = 〈xp〉 (p ≡ dx/dz being ...
