TL;DR: In this paper, the steady-state linear plasma device MPEX is designed to deliver those plasma conditions with a novel Radio Frequency plasma source able to produce high density plasmas and heat electron and ions separately with electron Bernstein wave (EBW) heating and ion cyclotron resonance heating with a total installed power of 800 kW.

TL;DR: The material plasma exposure experiment (MPEX) is a newly proposed steady state linear plasma device designed to deliver the necessary plasma heat flux to a target for testing, including the capability to expose a priori neutron-damaged material samples to those plasmas as discussed by the authors.
Journal ArticleDOI

Richard Goulding,John Caughman,Juergen Rapp,T. M. Biewer,T.S. Bigelow,I. H. Campbell,Juan Caneses,David Donovan,N. Kafle,Elijah Martin,H. Ray,G.C. Shaw,M. Showers +12 more
TL;DR: Proto-MPEX is a linear plasma device being used to study a novel RF source concept for the planned Material Plasma Exposure eXperiment (MPEX), which will address plasma-materials interaction (PMI) for nuclear fusion reactors as mentioned in this paper.
Journal ArticleDOI
Heat flux estimates of power balance on Proto-MPEX with IR imaging
TL;DR: The initial steps performed towards completing a power balance on Proto-MPEX to quantify where energy is lost from the plasma, including the relevant diagnostic package implemented are discussed.
Journal ArticleDOI
Direct measurement of the transition from edge to core power coupling in a light-ion helicon source
P. A. Piotrowicz,Juan Caneses,M. Showers,D. L. Green,Richard Goulding,John Caughman,T. M. Biewer,Juergen Rapp,David N. Ruzic +8 more
TL;DR: In this article, the authors present time-resolved measurements of an edge-to-core power transition in a light-ion (deuterium) helicon discharge in the form of infra-red camera imaging of a thin stainless steel target plate on the Proto-Material Exposure eXperiment device.
