The field array (200m x 200m) consists of 252 detector stations arranged on a rectangular grid with a distance of 13 meters to each other. 16 (resp. 15) of the stations form a so-called cluster with an electronics container in the center and which act as an independ shower experiment. In the middle of the array one can see the building with the KASCADE central detector.
In each station there are up to four electron/gamma-detectors and one muon-detector under a iron-lead-absorber of about 20 attenuation lengths. The absorber serves as shielding against the electomagnetic component of an extensive air shower. Only muons with energies greater than 250MeV are able to penetrate the absorber. The effective detection area per station is about 3.2m^2 for both detector types.
The two examples of KASCADE Array Events are screenshots from the Array Event Display. On the left sides of each event you see the energy deposits in the 252 Array stations, top the e/γ-detectors, bottom the μ-detectors. The warmer the color the higher the energy. On the right sides the corresponding arrival times. The warmer the color the bigger the time difference which usually corresponds to larger zenith angles.
