TL;DR: In this article, the existence of multi-pass extraction has been proven by blocking first pass extraction: using a crystal covered with an amorphous layer, extracted beam with high efficiency was observed, which provides a direct proof for the importance of the multispectral mechanism.

TL;DR: In this article, a detailed simulation of extensive air showers in atmosphere as produced by gammas and electrons has been performed by means of standard high energy physics Monte Carlo codes, with the aim to reduce the required computer power.
Abstract: The e.m. component of extensive air showers, as sampled at a given atmospheric depth, may be considered as the superposition of sub-showers initiated by photons and electrons (positrons) mainly coming from the decay of secondary mesons. A detailed simulation of showers in atmosphere as produced by gammas and electrons has been performed by means of standard high energy physics Monte Carlo codes. We developed a set of parametrizations of these sub-showers to be included in the full simulations of extensive air showers with the aim to reduce the required computer power. Comparisons with previous results found in the literature are shown.

TL;DR: In this paper, the production of target associated particles and of nuclear fragments in high energy hadron-nucleus interactions is studied based on a Monte Carlo realization of the Dual Parton Model.
Abstract: Based on a Monte Carlo realization of the Dual Parton Model we study the production of target associated particles and of nuclear fragments in high energy hadron-nucleus interactions. A formation zone intranuclear cascade of low energy secondaries inside the target nucleus is discussed. We calculate excitation energies of residual nuclei left after the intranuclear cascade process and treat their further disintegration by introducing models for the evaporation of protons, neutrons, and light fragments, high energy fission, and by applying a Fermi Break-up model to light nuclear fragments. The results are compared to data on target associated particle production. We furthermore calculate cross sections for the production of nuclear fragments.
