IEEE Transactions on Dielectrics and Electrical Insulation, 1996
A literature review on space-charge electrets, covering the time period 1987 to 1996, is presented. The review starts out with a discussion of new inorganic and organic electret materials which also includes silicon based single and double layers. This is followed by a review of recent work on methods for measuring charge distributions.

Solid-State Electronics, 1989
Abstract The non-local nature of impact ionization is modelled using lucky-drift theory with the assumption that the relevant electric field is the average field, but that the relevant drift velocity is that associated with the local field. The carrier density relevant for impact ionization is also taken to be non-local.

Physics Today, 1949
There is a good deal to physics besides nuclei, uncertainty, and relativity, as every hopeful student learns. Much of it, however, has disappeared from the forefront of science, some of it moving to the engineers, and the rest remaining mostly a storehouse of tools, useful in the free-for-all attack on the current frontier.

AIP Conference Proceedings, 2003
Based on a recent ICFA mini‐workshop held in Oxford, England [1], this paper surveys the computer codes available for simulating the behaviour of charged particle beams under space charge. Modelling tools for both linear and circular accelerating systems are covered. Lists of recent comparisons code v. code and code v. experiment are given and a set of

Space Charge between Parallel Planes
American Journal of Physics, 1954The problem of the potential distribution between two parallel planes at the same potential as a function of the current density passing between the planes is analyzed by successive approximation resulting in power series. The method involves a consideration of the influence of space charge on transit time, and the leading terms of the Maclaurin's ...

Space Charge Compensation with DCI
1980Extensive tests of space charge compensation, at the energy of.8 GeV, in similar conditions to those of the e+e− configuration are reported. Stability regions, smaller in size than those observed in that configuration, are found to decrease rapidly with current. Up to the limit, the beam cross-section stays constant.
