4.1 Space Charge and Image Effects 4.1.1 Incoherent Betatron Tune Shifts
"... The betatron tunes νz, z = x or y, of transverse oscillations of charged particles in the beam moving with axial velocity cv β = , c being the velocity of light, are mainly determined by the applied focusing forces due to quadrupoles. With finite beam current the tunes are shifted, both by direct sp ..."

On the virtues of parameterized uniform crossover
- In Proceedings of the Fourth International Conference on Genetic Algorithms
, 1991
"... Traditionally, genetic algorithms have relied upon I and 2-point crossover operators. Many recent empirical studies, however, have shown the benefits of higher numbers of crossover points. Some of the most intriguing recent work has focused on uniform crossover, which involves on the average Ll2 cro ..."

Effects of Wireless Physical Layer Modeling in Mobile Ad Hoc Networks
- in MobiHoc ’01: Proceedings of the 2nd ACM international symposium on Mobile ad hoc networking & computing
, 2001
"... In most studies on mobile ad hoc networks (MANET), simulation models are used for the evaluation of devices and protocols. Typically, such simulations focus on the specific higher layer protocols that are being proposed, and tend to ignore details of models at other layers, particularly the inter ..."

BETATRON TUNE SHIFT GENERATED SPECIFICALLY IN THE PRETZEL MACHINE
"... The well-known edge focusing effect of dipole fringe field has its natural continuation in the multipole phenomenology. Namely, entrance with an angle into quadrupole field gives some effective sextupole at the edge, entrance with an angle into sextupole field gives some effective octupole and so on ..."

Betatron x-ray production in mixed gases
"... Betatron x-rays with multi-keV photon energies have been observed from a GeV-class laser-plasma accelerator. The experiment was performed using the 200 TW Callisto laser system at LLNL to produce and simultaneously observe GeV-class electron beams and keV Betatron x-rays. The laser was focused with ..."

ELECTRON BEAM INJECTION, DEFLECTION, AND TRANSPORT IN THE UNM BETATRON
"... We present results from recent experiments on the generation of high-power relativistic electron beams using an upgraded injector and the subsequent injection and transport of these beams in the UNM Betatron. The experiments described were performed with peak beam energies of about 420 keV. The elec ..."

ANALYTICAL DESCRIPTION OF BETATRON OSCILLATIONS IN LINEAR MACHINES
"... As pointed out by Wiedemann, there are three basic periodic lattices using usually in storage rings [1,2]. Among these are the FODO, Chasman-Green lattice and triplet. They have not sextupole and octopole lenses and define so-called linear machines. To facilitate the calculations the consideration i ..."
