"Isotope identity experiments in JET-ILW"
45th European Physical Society Conference on Plasma Physics (EPS), Prague, 2-6 July 2018

CF Maggi H Weisen L Horvath F Auriemma R Lorenzini E. Delabie D King D Keeling S Menmuir JET Contributors

Dimensionless identity experiments test the invariance of plasma physics to changes in the dimensional plasma parameters, e.g. ne and Te, when the dimensionless parameters are conserved [1] [2]. However, conditions at the plasma boundary, such as influx of neutral particles, may introduce additional physics. An isotope identity experiment was ca…

"Instrumentation for the Upgrade to the JET Core Charge-Exchange Spectrometers"
22nd Topical Conference on High Temperature Plasma Diagnostics (HTPD), San Diego, USA, 16-19 April 2018

N. C. Hawkes E. Delabie S. Menmuir C. Giroud A. Meigs N. Conway T. M. Biewer D. L. Hillis

Charge-exchange spectroscopy on JET has become particularly challenging with the introduction of the ITER-like wall. The impurity spectra are weaker and contaminated by many tungsten lines. We have therefore upgraded the instrumentation to allow the simultaneous measurement of impurity and fuel-ion charge exchange by splitting the light between two…

"Neutral Beam Injection on JET : Effect on Neutron Deficit and Energy Balance"
45th European Physical Society Conference on Plasma Physics (EPS), Prague, 2-6 July 2018

D.B. King C.D. Challis E.G. Delabie D. Keeling G.F. Matthews S. Silburn JET contributors

The dependence of JET neutron deficit and energy balance on neutral beam (PINI) selection has been investigated experimentally. The discrepancy between neutrons predicted and measured during JET pulses has consistently deviated, with the measured neutrons typically being lower than expected by simulation. A number of investigations into this hav…
