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.
Antiprotons annihilating in emulsions and in silicon detectors, December 2012



After having been exposed to antiprotons, the photographic emulsion is scanned under an automatic microscope with depth of field of a few micron and each layer is digitized. The sequence of these layers (as the microscope scans into the depth of the emulsion) shows the annihilation fragments as they move outward from the annihilation point.
