Gauge transformations and quantum mechanics. III. The conventional interpretation of quantum mechanics. [Probabilities, causality, Lamb criterion]

Description: The gauge problem of the conventional interpretation of quantum mechanics is examined carefully within the framework of treating electromagnetic fields as classical and external quantities. It is found that the conventional interpretation not only is gauge dependent but also does not allow the degree of freedom of choosing a gauge in the Schroedinger equation. The fundamental approach to the gauge problem adopted is Lamb's criterion which states that the ''interaction'' Hamiltonian in a gauge c… more

Suppression of multiphoton excitation in resonance ionization measurements

Description: We describe experimental confirmation of strong suppressions of laser-driven nonlinear absorption processes by electromagnetic fields through other nonlinear processes within a given atomic or molecular medium. (AR)

FORTRAN programs for transient eddy current calculations using a perturbation-polynomial expansion technique

Description: A description is given of FORTRAN programs for transient eddy current calculations in thin, non-magnetic conductors using a perturbation-polynomial expansion technique. Basic equations are presented as well as flow charts for the programs implementing them. The implementation is in two steps--a batch program to produce an intermediate data file and interactive programs to produce graphical output. FORTRAN source listings are included for all program elements, and sample inputs and outputs are g… more

Harmonics suppression of vacuum chamber eddy current induced fields with application to the Superconducting Super Collider (SSC) Low Energy Booster (LEB) Magnets

Description: This memo presents the formulation of an expression for eddy currents induced in a thin-walled conductor due to a time-dependent electromagnet field excitation. Then follows an analytical development for prediction of vacuum chamber eddy current induced field harmonics in iron-core electromagnets. A passive technique for harmonics suppression is presented with specific application to the design of the Superconducting Super Collider (SSC) Low Energy B (LEB) Magnets.

Hot electron production, anomalous absorption, and effect of intense electromagnetic fields on inverse bremsstrahlung absorption near the electron plasma frequency

Description: Anomalous heating was studied on a well-controlled low-density plasma subjected to short microwave pulses. Absorption measurements along with parametric instabilities are described. The influence of intense ac electric fields on the electron-ion collision rate in the plasma is also discussed. (MOW)

Physics options in the plasma code VOA

Description: A two dimensional relativistic plasma physics code has been modified to accomodate general electromagnetic boundary conditions and various approximations of basic physics. The code can treat internal conductors and insulators, imposed electromagnetic fields, the effects of external circuitry and non-equilibrium starting conditions. Particle dynamics options include a full microscopic treatment, fully relaxed electrons, a low frequency electron approximation and a combination of approximations f… more

Experimental simulation of pulsed field losses in tokamak toroidal field coils

Description: Experiments have been carried out to measure loss in a twisted multifilamentary composite superconductor when exposed to a transient longitudinal field. We investigate the variation of losses both as a function of transverse applied field and of sample transport current. Losses are probed mainly by measurement of the dynamic resistivity of the sample during the longitudinal pulse. Experimental results are compared with theories for the zero transport current case. The extension of theory to inc… more

Magnetic field considerations in fusion power plant environs

Description: A summary of magnetic field production mechanisms and effects is given. Discussions are included on the following areas: (1) stray magnetic and electric fields from tokamaks, (2) methods for reducing magnetic fields, (3) economics of magnetic field reductions, (4) forces on magnetizable objects near magnetic confinement fusion reactors, (5) electric field transients in tokamaks, (6) attenuation and decay of electromagnetic fields, and (7) magnetic field transients from tokamak malfunctions.

Advanced Methods for the Computation of Particle Beam Transport and the Computation of Electromagnetic Fields and Beam-Cavity Interactions.

Description: The University of Maryland Dynamical Systems and Accelerator Theory Group has been carrying out long-term research work in the general area of Dynamical Systems with a particular emphasis on applications to Accelerator Physics. This work is broadly divided into two tasks: Charged Particle Beam Transport and the Computation of Electromagnetic Fields and Beam-Cavity Interactions. Each of these tasks is described briefly. Work is devoted both to the development of new methods and the application o… more

Experimental Studies on the Current Carrying Capacity of NbZr Wires Under Conditions of Fixed and Swept Magnetic Field

Description: Abstract: The current-carrying capacity of Nb- Zr wire has been studied under conditions of swept magnetic field and fixed wire current and of fixed magnetic field and swept wire current. The effects of wire movement, thermal environment, copper coating of the wire, and rate of sweep of wire current or magnetic field have been determined for these conditions of test.

Ionization in Crossed Electric and Magnetic Fields

Description: Both in magnetohydrodynamic shocks and in accelerated partially ionized gas flow across a magnetic field, space charge separation occurs that establishes very large electric fields in the direction of motion. The width of the current layers associated with the acceleration is never less than the electron Larmor radius with no collisions and is broadened by electron collisions to a width solely determined by the effective resistivity. The electrons gain an energy regardless of collisions equal t… more

On the Theory of the Compton Effect on a Meson

Description: The equations of Proka in the field of the plane wave are considered in this paper. When the energies of the incident quantum are large, a solution is reached in a closed form. On the basis of the solutions obtained, the diffusion of light on a meson is evaluated by the method of delayed potentials.
