Abstract
This paper presents a NPA (Neutral Particle Analysers) with noise rejection capability, based on the TOF coincidence technique, that has been designed, built, tested and fully calibrated in the Frascati ENEA (Italian Commission for New Technologies, Energy and Environment) laboratories and has been installed on JET mid 1990. The effectiveness of the time of flight (TOF) approach to noise rejection is discussed analytically and experimental evidence from the JET TOF NPA is shown. The advantage in the signal to noise ratio given by the TOF technique relative to other noise suppression methods is analysed, and the absence of significant systematic errors is stressed. The intrinsic flexibility of an instrument based on TOF mass analysis, and the possibility of performing cross tests both during calibration and operation on the tokamak are also discussed. The analyser has already shown, in the first experimental period on JET, its strong random noise rejection capability, with rejection factors in excellent agreement with basic probability theory estimates.
