Dense electron-positron plasmas and bursts of gamma-rays from laser-generated quantum electrodynamic plasmas

C. P. Ridgers, C. S. Brady, R. Duclous, J. G. Kirk, K. Bennett, T. D. Arber, and A. R. Bell

In simulations of a 12.5 PW laser (focussed intensity I = 4×1023Wcm−2) striking a solid aluminum target, 10% of the laser energy is converted to gamma-rays. A dense electron-positron plasma is generated with a maximum density of 1026m−3, seven orders of magnitude denser than pure e− e+ plasmas generated with 1PW lasers.

Cold atmospheric plasma in cancer therapy

Michael Keidar, Alex Shashurin, Olga Volotskova, Mary Ann Stepp, Priya Srinivasan, Anthony Sandler, and Barry Trink

Recent progress in atmospheric plasmas has led to the creation of cold plasmas with ion temperature close to room temperature. This paper outlines recent progress in understanding of cold plasma physics as well as application of cold atmospheric plasma (CAP) in cancer therapy.

Central peaking of magnetized gas discharges

Francis F. Chen and Davide Curreli

Partially ionized gas discharges used in industry are often driven by radiofrequency (rf) power applied at the periphery of a cylinder. It is found that the plasma density n is usually flat or peaked on axis even if the skin depth of the rf field is thin compared with the chamber radius a.

Landau damping in a turbulent setting

G. G. Plunk

To address the problem of Landau damping in kinetic turbulence, we consider the forcing of the linearized Vlasov equation by a stationary random source. It is found that the time-asymptotic density response is dominated by resonant particle interactions that are synchronized with the source.

Model of magnetic reconnection in space and astrophysical plasmas

Allen H. Boozer

Maxwell's equations imply that exponentially smaller non-ideal effects than commonly assumed can give rapid magnetic reconnection in space and astrophysical plasmas. In an ideal evolution, magnetic field lines act as stretchable strings, which can become ever more entangled but cannot be cut. High entanglement makes the lines exponentially sensitive to small non-ideal changes in the magnetic field.

Low-voltage gyrotrons

M. Yu. Glyavin, N. A. Zavolskiy, A. S. Sedov, and G. S. Nusinovich

For a long time, the gyrotrons were primarily developed for electron cyclotron heating and current drive of plasmas in controlled fusion reactors where a multi-megawatt, quasi-continuous millimeter-wave power is required. In addition to this important application, there are other applications (and their number increases with time) which do not require a very high power level, but such issues as the ability to operate at low voltages and have compact devices are very important.
