Abstract :
An iron sampling calorimeter for cosmic-ray hadrons used in the centre of a large air shower experiment is described. The iron absorber is interspersed with eight layers of ionisation chambers filled with the room-temperature liquids tetramethylsilane and tetramethylpentane. Experiences gained from the calorimeter, its performance and long-term stability are presented. For energies in the TeV range shower profiles and transition curves have been measured and are compared with Monte Carlo calculations employing the FLUKA code. Good agreement has been found except in the lateral halo region. In the outer regions the energy deposition found is smaller than that obtained by the simulations.
