Antiprotons annihilating in emulsions and in silicon detectors, December 2012
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.
Photos of the assembly of the AEgIS apparatus, November 2012
The assembly process included integration of the two magnets, insertion of the trapping electrodes
(Penning traps), installation of the laser system, installation of the scintilating fiber detector,
of the positronium test set-up, cabling, platforms, vacuum equipment, custom electronics, ...
Photos of the installation of the AEgIS apparatus, September 2012
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).

the AEgIS apparatus and equipment
Many components form the AEgIs apparatus; this gallery provides a slide show of the
equipment, the detectors and the people involved in building the experiment.
