Antiprotons annihilating in emulsions and in silicon detectors, December 2012

Annihilation of antiprotons in emulsion Vacuum chamber housing the emulsion and test moiré deflectomer

To test our detection process and characterize the detectors that form part of the combined antihydrogen detector that AEgIS will use, antiprotons available for a short time just as the main apparatus was completed at the end of 2012 were used to study antiproton annihilations in photographic emulsions and in silicon detectors. The test detectors and test moiré deflectometer were placed in a small vacuum chamber at the downstream end of the main apparatus which reduced the flux of antiprotons to a very small number.

The magnets (one 5T and one 1 T superconducting magnets) were constructed at CERN and insterted in cryostats (holding liquid helium and liquid nitrogen) and placed inside a vacuum vessel. These were then transported to the experimental area sited inside the Antiproton Decellerator (AD).
