Journal ArticleDOI
Helical plasma confinement devices with good confinement properties
TL;DR: The criterion of approximate omnigeneity (i.e., having bounce-averaged drift lying within the magnetic surfaces) is much easier to satisfy than quasihelicity, the condition that $B$, the magnitude of the magnetic field, is a function of only a single linear combination of the toroidal angles.
Journal ArticleDOI
Single-stage plasma-based correlated energy spread compensation for ultrahigh 6D brightness electron beams.
Grace Manahan,A. F. Habib,A. F. Habib,A. F. Habib,Paul Scherkl,Paul Scherkl,P. Delinikolas,P. Delinikolas,A. Beaton,Alexander Knetsch,Oliver Karger,G. Wittig,T. Heinemann,Zheng-Ming Sheng,John R. Cary,David L. Bruhwiler,James Rosenzweig,James Rosenzweig,Bernhard Hidding +18 more
TL;DR: By releasing an additional tailored escort electron beam at a later phase of the acceleration, when the witness bunch is relativistically stable, the plasma wave can be locally overloaded without compromising the witness lot normalized emittance, thus enabling the production of ultrahigh 6D-brightness beams.
Journal ArticleDOI
Ponderomotive force and linear susceptibility in Vlasov plasma
John R. Cary,Allan N. Kaufman +1 more
TL;DR: In this paper, the second-order Hamiltonian was derived from the ponderomotive force on the oscillation center of a particle in a high-frequency field and the standard linear Vlasov susceptibility.
Journal ArticleDOI
Correlations of periodic, area-preserving maps
James D. Meiss,John R. Cary,Celso Grebogi,John David Crawford,Allan N. Kaufman,Henry D. I. Abarbanel +5 more
TL;DR: In this paper, a simple analytical decay law for correlation functions of periodic, area-preserving maps is obtained, and the agreement between experiment and theory is good when islands are absent, but poor when they are present.
Journal ArticleDOI
Structure-preserving second-order integration of relativistic charged particle trajectories in electromagnetic fields
Adam Higuera,John R. Cary +1 more
TL;DR: In this article, a second-order method for integrating the relativistic momentum of charged particles in an electromagnetic field is derived, which is shown to have the same secondorder accuracy in time as that found by splitting the electric acceleration and magnetic rotation.
