Integrated circuits, manufactured in CMOS technology, have been developed as diffusion-based charged particle spectrometers for space applications. Current designs are single-chip spectrometers capable of uniquely identifying and counting electrons and heavy ions. A four-chip spectrometer designed to count protons and heavy ions was flown on the Clementine spacecraft. The spectrometer proton da...

This paper describes some computer-based activities to bring the study of charged particle optics to undergraduate students, to be performed as a part of a one-semester accelerator-based experimental course. The computational simulations were carried out using the commercially available SIMION program. The performance parameters, such as the focal length and P–Q curves are obtained. The three-e...

The main task of this work is to study, by means algebraic methods, the influence a constant and uniform magnetic field on classical dynamics an electrically charged particle. In text, we initially deal with Lorentz equation in 4-dimensional Minkowski spacetime. Also, Taylor series expansion relativistic factor its behavior Galileo's regime relativity are presented. Finally, equations motion pa...

We study the motion of a charged particle with magnetic moment in external electromagnetic fields utilizing covariant unification Gilbertian and Amperian descriptions dipole moment. Considering case current loop, our approach is verified by comparing classical dynamics limit relativistic quantum dynamics. obtain presence an linearly polarized EM (laser) plane wave field incorporating effect spi...

We investigate the conjectured bound on Lyapunov exponent for a charged particle with angular motion in Kerr-Newman-AdS black hole. The is calculated based effective Lagrangian. show that negative cosmological constant reduces chaotic behavior of particle, namely, it decreases exponent. Hence, more AdS spacetime than flat spacetime. Nevertheless, we find can be violated when momenta hole are tu...

The magnetic charge concept is further developed to define the vibrational motion of a charged particle moving in ether/dark matter. angular momentum resulting derived be ħ/2 at all velocities. also provides additional justification for Coulomb and gravitational forces not having singularity. Additional insights into antimatter composition annihilation are developed.

We study the slow singular limit for planar anharmonic oscillatory motion of a charged particle under the influence of a perpendicular magnetic field when the mass of the particle goes to zero. This model has been used by the authors as a toy model for exploring variational high order approximations to the slow dynamics in rotating fluids. In this paper, we address the long time validity of the...

A solution to a version of the Stieltjes moment problem is presented. Using this solution, we construct a family of coherent states of a charged particle in a uniform magnetic field. We prove that these states form an overcomplete set that is normalized and resolves the unity. By the help of these coherent states we construct the Fock-Bergmann representation related to the particle quantization...

One of the most often studied features of mesoscopic systems are the persistent currents in rings threaded by a magnetic flux – let us mention, e.g., [CGR, CWB] and scores of other theoretical and experimental papers where they were discussed. For a charged particle (an electron) confined to a loop Γ the effect is manifested by the dependence of the corresponding eigenvalues λn on the flux φ th...

We theoretically study the self-propulsion of a laser-heated Janus particle in a near-critical water-lutidine mixture, and we relate its velocity v_{p} and squirmer parameter β to the wetting properties of its two hemispheres. For nonionic surface forces, the particle moves the active cap at the front, whereas a charged hydrophilic cap leads to backward motion, in agreement with the experiment....
