Approximating rings with local units via automorphisms
(Springer Verlag, 1999-02)
For a ring A with local units we investigate unital overrings T of A, and compare the automorphism groups Aut(A) and Aut(T ).
Graded equivalence theory with applications
We develop the foundations for graded equivalence theory and apply them to investigate properties such as primeness, finite representation type, and vertex theory of graded rings. The key fact that we prove is that, for ...

Studies of ion acceleration in a one meter laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1991)
The basic concept behind the Laser Controlled Beamfront Experiment has been described in detail in previous reports(1,2) In the experiment, control over the propagation of a virtual cathode at the front of an intense ...

Periodic magnetic focusing of sheet electron beams
(American Institute of Physics, 1994-05)
Sheet electron beams focused by periodically cusped magnetic (PCM ) fields are stable against low-frequency velocity-shear instabilities (such as the diocotron mode). This is in contrast to the more familiar unstable ...
Intense charged particle beam propagation into vacuum
The propagation of intense charged particle beams into vacuum without the aid of externally applied confining magnetic fields is under investigation both theoretically and experimentally. In the configuration under study ...
Local orders whose lattices are direct sums of ideals
(American Mathematical Society, 1990-10)
Let R be a complete local Dedekind domain with quotient field K and let A be a local R-order in a separable K-algebra. This paper classifies those orders A such that every indecomposable R-torsionfree A-module is isomorphic ...

The design and feasibility of a I-MW continuous wave (CW) free electron laser (FEL) oscillator are reviewed. The proposed configuration will include a short-period (1" - I cm) planar wiggler. a sheet electron beam, a ...
