The Helical Wiggler
Kirk T. McDonald, Heinrich Mitter
There is not a unique solution to the electro- or magnetostatic problem where the "boundary condition" is merely a specification of the fields along a line. As a practical example,…
The Laser-Driven Vacuum Photodiode
Kirk T. McDonald
A vacuum photodiode driven by a pulsed laser can sustain an average current very similar to that of a continous diode, where the latter is described by Child's law.
The Grating Accelerator
Kirk T. McDonald
In optics, a reflective grating is a conducting surface with a ripple. The typical use of such a grating involves an incident electromagnetic wave with wave vector k in the x-z pla…
Energy Balance in an Electrostatic Accelerator
Max S. Zolotorev, Kirk T. McDonald
The principle of an electrostatic accelerator is that when a charge e escapes from a conducting plane that supports a uniform electric field of strength E_0, then the charge gains…
The Hawking-Unruh Temperature and Damping in a Linear Focusing Channel
Kirk T. McDonald
The Hawking-Unruh effective temperature, hbar a* / 2 pi c k, due to quantum fluctuations in the radiation of an accelerated charged-particle beam can be used to show that transvers…
Classical "Dressing" of a Free Electron in a Plane Electromagnetic Wave
Kirk T. McDonald, Konstantin Shmakov
The energy and momentum densities of the fields of a free electron in a plane electromagnetic wave include interference terms that are the classical version of the ``dressing'' of…
