- 01 Feb 2016
TL;DR: The new methodology described provides a complete neutron flux profile after a reactor pulse, utilizing fission chamber physics in combination with a compensating ion chamber to extract and convert a current signal to neutron flux as a function of time.
Ablation Simulation of Tungsten-Alternative Plasma-Facing Components due to Edge Localized Modes and Hard Disruptions
Jonathan Coburn,Mohamed Bourham +1 more
TL;DR: In this paper, the authors used a simulated electrothermal (ET) plasma to assess erosive behavior in preparation for future experiments at ORNL's high heat flux experiment and the DiMES experiments for induced disruption on the DIII-D tokamak.

Modeling Calibration and Verification of a Fission Chamber for ACRR.
Jonathan Coburn
- 01 Aug 2013
TL;DR: In this paper, the authors proposed a method of directly measuring neutron flux at the Annular Core Research Reactor (ACRR) by integrating the response of a fission chamber rate detection signal and then normalizing this integral to fluence determined from passive dosimetry.
