The 2016 Outstanding Student Poster and PICO (OSPP) Award is awarded to Stefan Meyer for the poster/PICO entitled:

Stefan Meyer is a PhD student at the Space Research and Planetary Sciences department of the Physics Institute at the University of Bern, Switzerland. He is developing the Neutral gas and Ion Mass spectrometer (NIM), which is part of the Particle Environment Package (PEP) carried by ESA’s L-class mission JUICE (JUpiter ICy moons Explorer). NIM will be used to measure the chemical composition of the atmospheres of the icy Jovian moons, as well as the ion composition of the ionospheres.
For the poster he presented at the EGU, measurements with the prototype instrument were performed in the neutral (open source) and thermal (closed source) mode. The results of these measurements with respect to fragmentation and density enhancements in the closed source mode are presented. Furthermore, a direct comparison between open and closed source mode measurements is given.
