Fast particle diagnostics at JET: status and plans

摘要: A comprehensive set of fast particle diagnostics is routinely used at JET. Some are in the process being upgraded and others, completely new, prepared for use during forthcoming tritium experiments. For fusion product studies, strength profile charged birth distribution obtained by measuring neutron emission with three pairs absolutely calibrated fission chambers a two-camera monitor. Information on DD energy spectrum deduced from time-of-flight spectrometer. Neutrons 14 MeV triton burnup measured using silicon diodes high branch Absolute calibration an activation system. prototype lost alpha detector (Faraday cup) has been tested laboratory installed inside JET so that its noise immunity can be tested. Two spectrometers under commissioning third construction. neutral analyser to diagnose RF driven particles will also available studies. The intensity spectroscopy gamma rays emitted reactions impurity ions plasma. ray monitor adds spatial resolution measurement. new antenna ion cyclotron (ICE) gyrotron scattering experiments commissioned. Active charge exchange investigate low range population considered. Where appropriate, information gathered these systems presented illustrate their performance
