Surface and Near-Surface Positron Annihilation Spectroscopy at Very Low Positron Energy
Lucian Mathes, Maximilian Suhr, Vassily V. Burwitz +3
We present a monoenergetic positron beam specifically tailored to the needs of (near-) surface positron annihilation spectroscopy. The Setup for LOw-energy Positron Experiments (SL…
Structure and Dynamics of Magneto-Inertial, Differentially Rotating Laboratory Plasmas
V. Valenzuela-Villaseca, L. G. Suttle, F. Suzuki-Vidal +9
We present a detailed characterization of the structure and evolution of differentially rotating plasmas driven on the MAGPIE pulsed-power generator (1.4 MA peak current, 240 ns ri…
On The Structure of Plasma Jets in the Rotating Plasma Experiment
V. Valenzuela-Villaseca, L. G. Suttle, F. Suzuki-Vidal +9
Recent pulsed-power experiments have demonstrated the formation of astrophysically-relevant, differentially rotating plasmas [1]. Key features of the plasma flows are the discovery…
Cooling and Instabilities in Colliding Radiative Flows with Toroidal Magnetic Fields
R. N. Markwick, A. Frank, E. G. Blackman +6
We report on the results of a simulation based study of colliding magnetized plasma flows. Our set-up mimics pulsed power laboratory astrophysical experiments but, with an appropri…
Radiative cooling effects on reverse shocks formed by magnetised supersonic plasma flows
S. Merlini, J. D. Hare, G. C. Burdiak +15
We study the structure of reverse shocks formed by the collision of supersonic, magnetised plasma flows driven by an inverse (or exploding) wire array with a planar conducting obst…
Morphology of Shocked Lateral Outflows in Colliding Hydrodynamic Flows
R. N. Markwick, A. Frank, J. Carroll-Nellenback +6
Supersonic interacting flows occurring in phenomena such as protostellar jets give rise to strong shocks, and have been demonstrated in several laboratory experiments. To study suc…
The structure of 3D collisional magnetized bow shocks in pulsed-power-driven plasma flow
Rishabh Datta, Danny R. Russell, Iek Tang +5
We investigate 3D bow shocks in a highly collisional magnetized aluminum plasma, generated during the ablation phase of an exploding wire array on the MAGPIE facility (1.4 MA, 240…
Time-resolved velocity and ion sound speed measurements from simultaneous bow shock imaging and inductive probe measurements
R. Datta, D. R. Russell, T. Clayson +3
We present a technique to measure the time-resolved velocity and ion sound speed in magnetized, supersonic high-energy-density plasmas. We place an inductive (`b-dot') probe in a s…
Investigating radiatively driven, magnetised plasmas with a university scale pulsed-power generator
Jack W. D. Halliday, Aidan Crilly, Jeremy Chittenden +8
We present first results from a novel experimental platform which is able to access physics relevant to topics including indirect-drive magnetised ICF; laser energy deposition; var…
Characterization of Quasi-Keplerian, Differentially Rotating, Free-Boundary Laboratory Plasmas
V. Valenzuela-Villaseca, L. G. Suttle, F. Suzuki-Vidal +9
We present results from pulsed-power driven differentially rotating plasma experiments designed to simulate physics relevant to astrophysical disks and jets. In these experiments,…
Perpendicular subcritical shock structure in a collisional plasma experiment
D. R. Russell, G. C. Burdiak, J. J. Carroll-Nellenback +13
We present a study of perpendicular subcritical shocks in a collisional laboratory plasma. Shocks are produced by placing obstacles into the super-magnetosonic outflow from an inve…
A Time-Resolved Imaging System for the Diagnosis of X-ray Self-Emission in High Energy Density Physics Experiments
Jack W. D. Halliday, Simon N. Bland, Jack D. Hare +4
A diagnostic capable of recording spatially and temporally resolved X-ray self emission data was developed to characterise experiments on the MAGPIE pulsed-power generator. The dia…
An Imaging Refractometer for Density Fluctuation Measurements in High Energy Density Plasmas
J. D. Hare, G. C. Burdiak, S. Merlini +9
We report on a recently developed laser-probing diagnostic which allows direct measurements of ray-deflection angles in one axis, whilst retaining imaging capabilities in the other…
Interactions of magnetized plasma flows in pulsed-power driven experiments
L G Suttle, G C Burdiak, C L Cheung +11
A supersonic flow of magnetized plasma is produced by the application of a 1 MA-peak, 500 ns current pulse to a cylindrical arrangement of parallel wires, known as an inverse wire…
Ion heating and magnetic flux pile-up in a magnetic reconnection experiment with super-Alfvenic plasma inflows
