Abstract
The design and main characteristics of combined shower spectrometers (CSSs) are presented: combined Cherenkov and lead-scintillation spectrometers that are intended for investigating shower processes in oriented crystals and that consist of ten independent lightproof counters with thicknesses of 1X and 1.18X, respectively. At an electron energy E = 26 GeV, the energy resolutions of both CSSs together with a Cherenkov spectrometer with a thickness of 15X, which was placed behind them, were 2.4 and 4.3% for the combined Cherenkov and lead-scintillation shower spectrometers, respectively.
