Short summary

We developed a prototype of the Neutral Gas and Ion Mass spectrometer (NIM) of the Particle Environment Package (PEP) for the JUICE mission of ESA. NIM will be used to measure the chemical composition of the exospheres of the icy Jovian moons. The NIM prototype was successfully tested under realistic conditions and we find that the closed source behaves as expected within the JUICE mission phase velocities. No additional fragmentation of the species recorded with the closed source is observed.
