I will persent the principle of Air \v Cerenkov techniques to detect astronomical very high energy gamma-rays. The CANGAROO experiment at southern hemisphere, as well as, the other experiments in the world are introduced. The results of the past and present experiments are briefly reviewed and also the future prospect of this techniques will be mentioned.

Beam test of a thin dual readout calorimeter for an experiment outside the Earth's atmospher 17:10 - 18:30

Cosmic ray experiments outside the Earth's atmosphere are subject to very severe restrictions on the mass of the instruments. In this paper, we describe tests of a thin (1.4 lambda deep) hadron calorimeter that was built in the context of prototype studies for the ACCESS experiment. This detector was equipped with two independent active
media, which provided complementary information on the showering hadrons. It is shown that by combining the information from these media it was possible to evaluate the em content event-by-event and thus reduce the effects of the dominant leakage fluctuations on the calorimeter performance

Parametrization of e and gamma initiated showes in lead glass calorimeter 17:50 - 18:10

A description of the response of the NOMAD electromagnetic calorimeter to electrons and photons is discussed. In particular the dependence of the two-dimensional shower shape on the angle and energy of the incident particle is parametrized by analytical functions. Some applications to the neutrino event reconstruction are also reported.
