From plasma to pattern: observation and characterization of periodic structure formation in dielectric breakdown channels of electron-irradiated insulators
Nick R. Schwartz, Bryson C. Clifford, Carolyn Chun +11
Dielectric breakdown of insulators is one of the most common failure modes of electronics in the high-radiation environment of space, but its mechanics remain poorly understood. Wh…
Half-life Measurements of Highly Charged Radioisotopes by Nuclear Recoil in a Penning Trap
Scott Moroch, Carolyn Chun, Doug VanDerwerken +4
We present a novel method for measuring the half-life of highly charged radioisotopes by non-destructive nuclear recoil detection in a Penning ion trap. A specific emphasis is plac…
Electrically insulating materials for centrifugal mirrors
Nick R. Schwartz, Carlos A. Romero-Talamás, Marlene I. Patino +10
The centrifugal mirror confinement scheme incorporates supersonic rotation into a magnetic mirror device, which stabilizes and heats the plasma. This concept is under investigation…
Measurements of Fusion Yield on the Centrifugal Mirror Fusion Experiment
John L. Ball, Shon Mackie, Jacob G. van de Lindt +9
The Centrifugal Mirror Fusion Experiment (CMFX) at the University of Maryland, College Park is a rotating mirror device that utilizes a central cathode to generate a radial electri…
Myths of Nuclear Graphite in World War II, with Original Translations
Patrick J. Park, Sebastian Herzele, Timothy W. Koeth
We re-examine a common narrative that experimental errors by Walther Bothe in 1941 led Germany to abandon graphite as a reactor moderator during World War II. Using document-based…
