The favourite picture of FAIR and GSI


Our FAIR-GSI favourite pictures are chosen! Around 500 people took part and voted for their favorites out of 50 photos. The then photos with the most votes are compiled on our favourite picture website. We will also present these pictures in an exhibition on the GSI and FAIR campus in the KBW foyer at the end of the year.

Our first place with a total of 87 votes is a picture by photographer Thomas Ernsting showing the large-scale detector FOPI. For high-energy research with the particle accelerator SIS18, which can bring heavy ions up to 90 percent of the speed of light, new detectors were put into operation in the 1990s, including FOPI (4Pi) — a detector that covers almost the entire solid angle. The aim of FOPI was to investigate the hot, dense nuclear matter that is produced for a very short time during a high-energy heavy ion collision. It expands explosively and emits newly produced particles. FOPI was designed by an international collaboration of 13 institutes and operated at GSI until a few years ago.

The photo on place 2 with 77 votes was taken by Christian Grau. It was produced on the occasion of our Open House in 2017 and shows a girl looking through an accelerator structure of our linear accelerator UNILAC. With 11,000 visitors, the Open House was the largest event in the history of GSI and FAIR. Place 3 with 63 votes, also by Thomas Ernsting, opens a view into our large-scale detector HADES. HADES (High Acceptance Di-Electron Spectrometer) is used to investigate hot, dense nuclear matter, among other things to answer the question of mass. It is not yet clear why a proton has significantly more mass than its individual components. HADES will continue to be used at FAIR as a component of the CBM detector for the investigation of compressed nuclear matter.

The ten winners of the GSI coffee cups "The Universe in the Lab" from our prize draw have been notified of their prize via e-mail. (CP)
