A Megavoltmeter for Induction Electron Accelerators

Review of Scientific Instruments, 1946
A direct reading instrument is described for showing the electron voltage to which the induction electron accelerator is adjusted in correlation to operating voltage of the machine and phase of the orbit shift circuit.

Production of electron trees with a clinical electron accelerator

Australasian Physics & Engineering Sciences in Medicine, 2004
Simple methods for generating 'electron trees' (patterns of charge deposition and discharge in a low-conducting medium) with a modified clinical electron accelerator are described.

On the Classical Radiation of Accelerated Electrons

Physical Review, 1949
This paper is concerned with the properties of the radiation from a high energy accelerated electron, as recently observed in the General Electric synchrotron. An elementary derivation of the total rate of radiation is first presented, based on Larmor's formula for a slowly moving electron, and arguments of relativistic invariance. We then construct an

High energy electron accelerators

1958 IRE International Convention Record, 1964
The Cambridge Electron Accelerator is now in full-scale operation for research at energies up to 6 Bev, five times higher than earlier electron accelerators. The machine, a synchrotron, uses a ring of 48 alternating gradient magnets in a circle 236 feet in diameter.

GPU‐accelerated computation of electron transfer

Journal of Computational Chemistry, 2012
AbstractElectron transfer is a fundamental process that can be studied with the help of computer simulation. The underlying quantum mechanical description renders the problem a computationally intensive application. In this study, we probe the graphics processing unit (GPU) for suitability to this type of problem.

Electron Optics in Accelerating Tubes

Journal of Applied Physics, 1962
The focusing properties of the multi-stage system of weak lenses, such as in the accelerating tubes, are considered. The lens system is treated as one thick lens in the paraxial ray approximations. By assuming that the field distribution of each lens is the same, the simple expressions for the focal lengths and the locations of the focal points of this

Electronic equipment for an electron analogue accelerator

Transactions of the Institute of Radio Engineers Professional Group on Nuclear Science, 1954
An electron analogue accelerator 45 feet in diameter is being constructed to test a variety of orbital properties of a strong-focusing synchrotron system. High-voltage sawtooth wave generators will supply the electrostatic bending and correcting lenses.

Laser Electron Accelerator

Physical Review Letters, 1979
An intense electromagnetic pulse can create a weak of plasma oscillations through the action of the nonlinear ponderomotive force. Electrons trapped in the wake can be accelerated to high energy. Existing glass lasers of power density ${10}^{18}$W/${\mathrm{cm}}^{2}$ shone on plasmas of densities ${10}^{18}$ ${\mathrm{cm}}^{\ensuremath{-}3}$ can yield ...

Transresonant electron acceleration

Journal of Geophysical Research, 1961
Helliwell and Bell have suggested synchronous acceleration of electrons by electromagnetic waves in the whistler range in the geomagnetic field. The acceleration of trapped electrons by electromagnetic waves is here generalized to include nonsynchronous or transresonant acceleration.

A Russian Electron Accelerator

Nature, 1967
Of the two high energy accelerators now nearing completion in the Soviet Union, that at Yerevan in Armenia is the furthest advanced. It was recently visited by a party of British journalists.
