“…7 we show the cascade curves for electrons calculated for different values of the primary (ε 0 ) and threshold (ε th ) energies using the adjoint equation technique. For comparison we also show the cascade curves calculated within the approximation A of the analytical theory of electromagnetic cascades [1] (valid for ε th ≫ ε cr ), as well as the cascade curves obtained by Monte Carlo simulations using the ALTAI code [37]. The results obtained by 3 different methods are in a good agreement with each other.…”

“…The calculations are performed for the following primary energies ε 0 = 2 • 10 8 (curve 1), 2 • 10 7 (curve 2), 2 • 10 4 (curve 3) and the ratio ε th /ε cr = 125 (curves 1 and 2), 0.05 (curve 3). For comparison, the results derived from the analytical cascade theory [1] (boxes) and by simulations with the ALTAI code [37] (triangles) are also shown photon gas with a broad band energy distribution this parameter becomes meaningless. At the same time in a narrow band radiation fields, e.g.…”

We investigate the properties of astrophysical electromagnetic cascades in matter, photon gas and magnetic fields, and discuss similarities and differences between characteristics of electron-photon showers developed in these 3 substances. We apply the same computational technique based on solution of the adjoint cascade equations to all 3 types of cascades, and present precise numerical calculations of cascade curves and broad-band energy spectra of secondary electrons and photons at different penetration lengths.

“…Atmospheric showers induced by c-rays, electrons, and protons have been simulated using a numerical code described by Konopelko and Plyasheshnikov [23]. The primary energy of simulated showers was sampled as uniformly distributed within each of 24 bins, which were chosen within the energy range starting from 1 GeV and extending up to 10 TeV.…”

“…The results discussed in this section have been obtained by using the AL-TAI code [19] that simulates electromagnetic and hadronic showers and their Cherenkov radiation in the Earth's atmosphere. This code has been used before for calculations of the performance of the HEGRA system of IACTs [8], as well as for studies of the expected characteristics of the new generation "100 GeV -threshold" IACT arrays [6] that are the basis of the H.E.S.S.…”

We discuss the concept and the performance of a powerful future ground-based astronomical instrument, 5@5 -a 5 GeV energy threshold stereoscopic array of several large imaging atmospheric Cherenkov telescopes installed at a very high mountain elevation of about 5 km a.s.l. -for the study of the γ-ray sky at energies from approximately 5 GeV to 100 GeV, where the capabilities of both the current space-based and ground-based γ-ray projects are quite limited. With its potential to detect the "standard" EGRET γ-ray sources with spectra extending beyond several GeV in exposure times from 1 to 10 3 seconds, such a detector may serve as an ideal "Gamma-Ray Timing Explorer" for the study of transient non-thermal phenomena like γ-radiation from AGN jets, synchrotron flares of microquasars, the high energy (GeV) counterparts of Gamma Ray Bursts, etc. 5@5 also would allow detailed γ-ray spectroscopy of persistent nonthermal sources like pulsars, supernova remnants, plerions, radiogalaxies, and others, with unprecedented for γ-ray astronomy photon statistics. The existing technological achievements in the design and construction of multi (1000) pixel, high resolution imagers, as well as of large, 20 m diameter class multi-mirror dishes with rather modest optical requirements, would allow the construction of such a detector in the foreseeable future, although in the longer terms from the point of view of ongoing projects of 100 GeV threshold IACT arrays like H.E.S.S. which is in the build-up phase. An ideal site for such an instrument could be a high-altitude, 5 km a.s.l or more, flat area with a linear scale of about 100 m in a very arid mountain region in the Atacama desert of Northern Chile.
