Photonic-Band-Gap Gyrotron Amplifier with Picosecond Pulses
Emilio A. Nanni, Sudheer Jawla, Samantha M. Lewis +2
We report the amplification of 250~GHz pulses as short as 260~ps without observation of pulse broadening using a photonic-band-gap circuit gyrotron traveling-wave-amplifier. The gy…
SOFT: A synthetic synchrotron diagnostic for runaway electrons
Mathias Hoppe, Ola Embréus, R. Alexander Tinguely +3
Improved understanding of the dynamics of runaway electrons can be obtained by measurement and interpretation of their synchrotron radiation emission. Models for synchrotron radiat…
Collisionless Reconnection in Magnetohydrodynamic and Kinetic Turbulence
N. F. Loureiro, S. Boldyrev
It has recently been proposed (Loureiro & Boldyrev 2017; Mallet et al. 2017) that the inertial interval in magnetohydrodynamic (MHD) turbulence is terminated at small scales not by…
A positive-definite form of bounce-averaged quasilinear velocity diffusion for the parallel inhomogeneity in a tokamak
Jungpyo Lee, David Smithe, John Wright +1
In this paper, the analytical form of the quasilinear diffusion coefficients is modified from the Kennel-Engelmann diffusion coefficients to guarantee the positive definiteness of…
Cooling and entanglement of multimode graphene resonators via vacuum fluctuations
Sofia Ribeiro, Hugo Terças
Sympathetic laser cooling of a single mode graphene membrane coupled to an atomic cloud interacting via Casimir-Polder forces has been recently proposed. Here, we extend this study…
Magnetohydrodynamic turbulence mediated by reconnection
Stanislav Boldyrev, Nuno F. Loureiro
Magnetic field fluctuations in MHD turbulence can be viewed as current sheets that are progressively more anisotropic at smaller scales. As suggested by Loureiro & Boldyrev (2017)…
