The AD hall experimental area at CERN

The Antiproton Decelerator is a ring like structure of 50m times 60m which is situated on the lower level (actually it is something like 10 m below street level). All the experiments are located in this ring. Both the ASACUSA and ATHENA experiment are at the same level as the AD, but our experiment  is on a 3 meter high platform. The advantage of this platform is that the antiprotons can be bend and directed upwards. This allows for vertical injection into the Penning trap and its superconducting magnet. This has many advantages for the construction of the superconducting magnet and the handling of the trap.
