  An Imaging Neutral Particle Analyser (INPA) diagnostic has been designed for
the ASDEX Upgrade (AUG) tokamak. The AUG INPA diagnostic will measure fast
neutrals escaping the plasma after CX reactions. The neutrals will be ionised
by a 20 nm carbon foil and deflected towards a scintillator by the local
magnetic field. The use of a neutral beam injector (NBI) as active source of
neutrals will provide radially resolved measurements while the use of a
scintillator as active component will allow us to cover the whole plasma along
the NBI line with unprecedented phase-space resolution ($ < $ 12 keV and 8 cm)
and fast temporal response (up to 1 kHz with the high resolution acquisition
system and above 100 kHz with the low resolution one); making it suitable to
study localised fast-ions redistributions in phase-space.
