Datta R, Chandler K, Myers C, Chittenden J, Crilly A, Aragon C, et al.
Phys Rev Lett . 2024 Apr; 132(15):155102. PMID: 38683000
We present the first experimental study of plasmoid formation in a magnetic reconnection layer undergoing rapid radiative cooling, a regime relevant to extreme astrophysical plasmas. Two exploding aluminum wire arrays,...

Pearcy J, Rosenberg M, Johnson T, Sutcliffe G, Reichelt B, Hare J, et al.
Phys Rev Lett . 2024 Feb; 132(3):035101. PMID: 38307081
Magnetic reconnection is a ubiquitous and fundamental process in plasmas by which magnetic fields change their topology and release magnetic energy. Despite decades of research, the physics governing the reconnection...

Valenzuela-Villaseca V, Suttle L, Suzuki-Vidal F, Halliday J, Merlini S, Russell D, et al.
Phys Rev Lett . 2023 May; 130(19):195101. PMID: 37243644
We present results from pulsed-power driven differentially rotating plasma experiments designed to simulate physics relevant to astrophysical disks and jets. In these experiments, angular momentum is injected by the ram...

Russell D, Burdiak G, Carroll-Nellenback J, Halliday J, Hare J, Merlini S, et al.
Phys Rev Lett . 2022 Dec; 129(22):225001. PMID: 36493430
We present a study of perpendicular subcritical shocks in a collisional laboratory plasma. Shocks are produced by placing obstacles into the supermagnetosonic outflow from an inverse wire array z pinch....

Datta R, Russell D, Tang I, Clayson T, Suttle L, Chittenden J, et al.
Rev Sci Instrum . 2022 Nov; 93(10):103530. PMID: 36319372
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 supersonic pulsed-power-driven plasma flow...

Hare J, Burdiak G, Merlini S, Chittenden J, Clayson T, Crilly A, et al.
Rev Sci Instrum . 2021 Apr; 92(3):033521. PMID: 33820051
We report on a recently developed laser-probing diagnostic, which allows direct measurements of ray-deflection angles in one axis while retaining imaging capabilities in the other axis. This allows us to...

Suttle L, Hare J, Halliday J, Merlini S, Russell D, Tubman E, et al.
Rev Sci Instrum . 2021 Apr; 92(3):033542. PMID: 33819991
Optical collective Thomson scattering (TS) is used to diagnose magnetized high energy density physics experiments at the Magpie pulsed-power generator at Imperial College London. The system uses an amplified pulse...

Elle E, Hare J
Oecologia . 2017 Mar; 123(1):57-65. PMID: 28308744
Populations of Datura wrightii vary in the frequency of plants that produce glandular trichomes, a resistance trait under the control of a single gene. Such variation may be maintained if...

Hare J, Suttle L, Lebedev S, Loureiro N, Ciardi A, Burdiak G, et al.
Phys Rev Lett . 2017 Mar; 118(8):085001. PMID: 28282176
We present a detailed study of magnetic reconnection in a quasi-two-dimensional pulsed-power driven laboratory experiment. Oppositely directed magnetic fields (B=3  T), advected by supersonic, sub-Alfvénic carbon plasma flows (V_{in}=50  km/s),...

Suttle L, Hare J, Lebedev S, Swadling G, Burdiak G, Ciardi A, et al.
Phys Rev Lett . 2016 Jun; 116(22):225001. PMID: 27314720
We present experiments characterizing the detailed structure of a current layer, generated by the collision of two counterstreaming, supersonic and magnetized aluminum plasma flows. The antiparallel magnetic fields advected by...
