Cullwick’s Paradox: Charged Particle on the Axis of a Toroidal Magnet
نویسندگان
چکیده
In an induction linac [1] a toroidal solenoid magnet carries a time-dependent current I(t) such that the induced electric field can transfer energy from the magnet to charged particles that move along the axis of the toroid. Discuss the force and momentum balance in an idealized induction linac consisting of a single magnet whose form is a torus of major radius a and minor radius b a, and a single electron of charge e that moves along the symmetry axis of the toroid. The current I is the total current crossing any major circle on the surface of the torus.

McKenna’s Paradox: Charged Particle Exiting the Side of a Solenoid Magnet
The “science fact” section of the March 1965 issue of Analog magazine featured an article by Richard P. McKenna that proposed a “motor” which would consist of a solenoid magnet that can rotate about its axis, plus a radioactive source mounted on that axis [1]. When a charged particle is emitted by a radioactive decay it traverses the solenoid field, which bends the particle’s trajectory, giving...
متن کاملComparison of the Eccentricity Faults Effects on the Performance of several Toroidal Wounded Axial Flux Permanent Magnet Motors
Eccentricity fault is one the most common fault types of disk-type permanent magnet machines, which could lead to devastating effects. Unfortunately, most of the previous works have studied this fault and its detection techniques for slotted structure with common winding. Therefore, in this paper, the effects of eccentricity faults on the performance of single-sided slotted, single-sided slotle...
متن کاملSuspension of a field-cooled BiPbSrCaCuO high-Tc superconductor under a toroidal permanent magnet
Magnetic flux measurements of a toroidal magnet revealed a concave-shaped field distribution with a single minimum and a null field along the axis of the torus at the point where the field reversed. The non-linear magnetic field of the toroidal magnet perpendicular to the Ag2O-doped superconducting disc sample with trapped magnetic flux distorted the field line distribution. As a result, the in...
متن کاملModelling and Optimization of Toroidal Continuously Variable Transmission in ECE Driving Cycle
In the present study, the aim is to optimize full and half toroidal continuously variable transmission (CVT) in order to minimize the vehicle fuel consumption (FC) in ECE driving cycle. First, the model of both CVTs’ efficiency is presented. The control strategy of CVTs speed ratio based on minimizing the vehicle FC is introduced, and the algorithm of calculating the vehicle FC is shown. Afterw...
متن کاملPhysics with Jets at the Lhc ∗
The CERN Large Hadron Collider (LHC) is designed to study pp collisions at a center-of-mass energy of 14 TeV and luminosity of 10cms. The GHz collision rate with 20 interactions per 25 ns bunch crossing places unprecedented demands on detector performance. This report will concentrate on jet physics anticipated from the two big general purpose detectors, a toroidal large hadron collider apparat...
