Tungsten is a promising material for the plasma-facing components of nuclear fusion
reactors due to its resistance to heat flux and plasma influence. However, a transient heating …

Tungsten is a candidate divertor material for many tokamak reactors and has potential to be
durable to high heat flux conditions. However, plasma-materials interaction and edge …

A digital holography (DH) surface erosion/deposition diagnostic is being developed for 3D
imaging of plasma facing component surfaces in situ and in real time. Digital holography is a …

Tungsten materials are subjected to severe damage when exposed to transient high heat
loads, and the crack initiation and propagation are observed experimentally based on the …

To produce a realistic tokamak-like plasma environment in linear plasma device, a transient
source is needed to deliver heat and particle fluxes similar to those seen in an edge …

There are currently few viable diagnostic techniques for in situ measurement of plasma
facing component erosion. Digital holography is intended to fill this gap. Progress on the …

Digital holography has been proposed to fulfill a need for an imaging diagnostic capable of
in situ monitoring of surface erosion caused by plasma–material interaction in nuclear fusion …

A diagnostic system, which has a design goal of high-portability, has been designed at Oak
Ridge National Laboratory (ORNL). This project aims at providing measurements of key …

The behavior of the transient heat flux produced by a three-electrode capillary discharge
generator working at a repetitive mode is presented in this paper. The radial distribution …
