HADES Detector with Camera for the Cherenkov Effect (image) Technical University of Munich (TUM) Share Print E-Mail Caption HADES detector with digital camera that records light patterns originating from virtual photons. The detector is suitable for investigating the properties of atomic nuclei under high pressure, just as it is produced in a supernova. This allows conclusions to be drawn as to how mass is formed in the first place.
