Effect of scintillator geometry on the energy resolution and efficiency of MAST neutron camera detectors
Marco Cecconello
The efficiency and energy resolution of the MAST neutron camera detectors, based on liquid scintillator of the EJ-301 type, is lower than cylindrical detector of similar size. An e…
Validation of neutron emission and neutron energy spectrum calculations on MAST with DRESS
Andrea Sperduti, Iwona Klimek, Sean Conroy +3
The recently developed Directional RElativistic Spectrum Simulator (DRESS) code has been validated for the first time against numerical calculations and experimental measurements p…
Global scaling of the heat transport in fusion plasmas
Sara Moradi, Johan Anderson, Michele Romanelli +2
A global heat flux model based on a fractional derivative of plasma pressure is proposed for the heat transport in fusion plasmas. The degree of the fractional derivative of the he…
Strategy and guidelines for the calibration of the ITER radial neutron camera
M. Cecconelloa, R. Miklaszewski, D. Marocco +6
A calibration procedure is proposed for the ITER Radial Neutron Camera. No in-vessel calibration using external neutron sources is required: instead, it is proposed to rely on embe…
Liquid scintillators neutron response function: a tutorial
M. Cecconello
This tutorial is devoted to the understanding of the different components that are present in the neutron light output pulse height distribution of liquid scintillators in fusion r…
Overview of recent physics results from MAST
A Kirk, J Adamek, RJ Akers +160
New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion…
Mitigation of MHD induced fast-ion redistribution in MAST and implications for MAST-Upgrade design
D L Keeling, T R Barrett, M Cecconello +9
The phenomenon of redistribution of neutral beam fast-ions due to MHD activity in plasma has been observed on many tokamaks and more recently has been a focus of research on MAST (…
Bi-directional Alfvén Cyclotron Instabilities in the Mega-Amp Spherical Tokamak
S. E. Sharapov, M. K. Lilley, R. Akers +6
Alfvén cyclotron instabilities excited by velocity gradients of energetic beam ions were investigated in MAST experiments with super-Alfvénic NBI over a wide range of toroidal magn…
Measurements and modelling of fast-ion redistribution due to MHD instabilities in the Mega-Amp Spherical Tokamak
O M Jones, C A Michael, M Cecconello +10
The results of a comprehensive investigation into the effects of various MHD modes on the NBI-generated fast-ion population in MAST plasmas are reported. Fast-ion redistribution du…
Measurement and control of the fast ion redistribution on MAST
M. Turnyanskiy, C. D. Challis, R. J. Akers +7
Previous experiments on MAST and other tokamaks have indicated that the level of fast ion redistribution can exceed that expected from classical diffusion and that this level incre…
