Description

The formation of electromagnetic showers in single crystals has been investigated experimentally. The multiplicity of charged particles in the shower is deduced from the energy deposited in a semiconductor detector. The showers are found to develop much faster along axial directions than far from axes. Based on this effect, the construction of compact electromagnetic calorimeters for very high energy gamma rays, using aligned single crystals as converters, is suggested. (orig.)
