Absolute keV X-ray yield and conversion efficiency in over dense Si petawatt laser plasma
Sergey N. Ryazantsev, Artem S. Martynenko, Maksim V. Sedov +15
Laser-produced plasmas are bright, short sources of X-rays often used for time-resolved imaging and spectroscopy. Absolute measurement requires accurate knowledge of laser-to-x-ray…
The data-driven future of high energy density physics
Peter W. Hatfield, Jim A. Gaffney, Gemma J. Anderson +20
The study of plasma physics under conditions of extreme temperatures, densities and electromagnetic field strengths is significant for our understanding of astrophysics, nuclear fu…
Identification of electrostatic two-stream instabilities associated with a laser-driven collisionless shock in a multicomponent plasma
Youichi Sakawa, Yutaka Ohira, Rajesh Kumar +3
Electrostatic two-stream instabilities play essential roles in an electrostatic collisionless shock formation. They are a key dissipation mechanism and result in ion heating and ac…
Gamma-Ray Flash in the Interaction of a Tightly Focused Single-Cycle Ultraintense Laser Pulse with a Solid Target
P. Hadjisolomou, T. M. Jeong, P. Valenta +5
We employ the regime where a near-single-cycle laser pulse is tightly focused, thus providing the highest possible intensity for the minimal energy at a certain laser power.…
Linear gyrokinetic stability of a high non-inductive spherical tokamak
B. S. Patel, D. Dickinson, C. M. Roach +1
Spherical tokamaks (STs) have been shown to possess properties desirable for a fusion power plant such as achieving high plasma ? and having increased vertical stability. To unders…
Surface production of negative ions from pulse-biased nitrogen doped diamond within a low-pressure deuterium plasma
Gregory J. Smith, Lenny Tahri, Jocelyn Achard +4
The production of negative ions is of significant interest for applications including mass spectrometry, materials surface processing, and neutral beam injection for magnetic confi…
Extended electron tails in electrostatic microinstabilities and the nonadiabatic response of passing electrons
M. R. Hardman, F. I. Parra, C. Chong +6
Ion-gyroradius-scale microinstabilities typically have a frequency comparable to the ion transit frequency. Due to the small electron-to-ion mass ratio and the large electron trans…
The role of plasma-molecule interactions on power and particle balance during detachment on the TCV tokamak
Kevin Verhaegh, Bruce Lipschultz, James Harrison +14
This paper shows experimental results from the TCV tokamak that indicate plasma-molecule interactions involving and possibly play an important role as sinks of energy…
Proton Radiography in Background Magnetic Fields
Christopher Arran, Christopher P. Ridgers, Nigel C. Woolsey
Proton radiography has proved increasingly successful as a diagnostic for electric and magnetic fields in high energy density physics experiments. Most experiments use target-norma…
A laser-plasma platform for photon-photon physics
B. Kettle, D. Hollatz, E. Gerstmayr +35
We describe a laser-plasma platform for photon-photon collision experiments to measure fundamental quantum electrodynamic processes such as the linear Breit-Wheeler process with re…
Highly efficient conversion of laser energy to hard X-rays in high intensity laser-solid simulations
Stuart Morris, Alex Robinson, Christopher Ridgers
We present simulations which predict significantly higher laser to X-ray efficiencies than those previously found in high intensity (1e20-1e22 W/cm2) laser-solid simulations. The b…
On Ohm's law in reduced plasma fluid models
B. D. Dudson, S. L. Newton, J. T. Omotani +1
Drift-reduced MHD models are widely used to study magnetised plasma phenomena, in particular for magnetically confined fusion applications, as well as in solar and astrophysical re…
Measurement of magnetic cavitation driven by heat flow in a plasma
Christopher Arran, Adam Dearling, Philip Bradford +13
We describe the direct measurement of the expulsion of a magnetic field from a plasma driven by heat flow. Using a laser to heat a column of gas within an applied magnetic field, w…
Bright betatron radiation from direct-laser-accelerated electrons at moderate relativistic laser intensity
O. N. Rosmej, X. F. Shen, A. Pukhov +8
Direct laser acceleration (DLA) of electrons in a plasma of near critical electron density (NCD) and associated synchrotron-like radiation are discussed for moderate relativistic l…
Ion acceleration at two collisionless shocks in a multicomponent plasma
Rajesh Kumar, Youichi Sakawa, Takayoshi Sano +3
Intense laser-plasma interactions are an essential tool for the laboratory study of ion acceleration at a collisionless shock. With two-dimensional particle-in-cell calculations of…
Comparing Two- and Three-Dimensional Models of Scrape-Off-Layer Turbulent Transport
T. E. G. Nicholas, J. Omotani, F. Riva +2
There exists a large body of previous work using reduced two-dimensional models of the SOL, which model fluctuations in the drift-plane but approximate parallel transport with effe…
