摘要: An experiment with the aim of determining neutron field characteristics for high performance discharges is being carried out on JET tokamak. The parameters (yield, fluence, energy distribution) at a specific location outside Torus Hall are to be measured simultaneously by three independent techniques (super-heated fluid detectors or “bubble detectors”, activation, and time-of-flight). Eventually results compared transport calculations. bubble detector activation measurement situated end vertical collimated line sight, behind TOFOR [1] time-of-flight spectrometer. field-of-view can varied means pre-collimator.
