Antiprotons annihilating in emulsions and in silicon detectors, December 2012 
After having scanned the developed emulsion under a microscope with depth of field of a few micron and digitized each layer, we can reconstruct the position in 3D of each point on the tracks that the fragments took, and transform this information into a 3D image that can be rotated to see the annihilation event from all angles.
