        "Description": "The Neutral Particle Imager (NPI) of the ASPERA-4 package\r\nflown on Venus Express provides measurements of the integral ENA flux with no \r\nmass and energy resolution but with 4.6 deg x 11.5 deg angular resolution. The \r\nintrinsic field of view is 9 deg x 344 deg. The sensor utilizes a graphite surface \r\nto suppress the UV background. ENAs incident on the surface at a grazing angle of \r\n20 deg are reflected and/or cause ion sputtering. An MCP stack detects the reflected \r\nparticles and sputtered fragments with a discrete anode.",
