G. Fehrenbacher, F. Gutermuth, T. Radon GSI Darmstadt, Germany An important aspect to be considered when designing the GSI future project will be the radiation protection of both the staff and the environment. One of the prerequisites for a permission for the operation of a high-energy accelerator is a careful planning of the necessary radiation shielding equipment. In order to give recommendat...

The KASCADE experiment measures extensive air showers induced by cosmic rays in the energy range around the so-called knee. The data of KASCADE have been used in a composition analysis showing the knee at 3–5 PeV to be caused by a steepening in the light-element spectra [1]. Since the applied unfolding analysis depends crucially on simulations of air showers, different high energy hadronic inte...

Background: The dosimetric parameters required in lung cancer radiation therapy are taken from a homogeneous water phantom; however, during treatment, the expected results are being affected because of its inhomogeneity. Therefore, it becomes necessary to quantify these deviations.Objective: The present study has been undertaken to find out inter- and intra- lung density variations and its dosi...

Every 10 s, the antiproton-production-target will be bombarded by a pulse of 2×10 primary protons with an energy of 29 GeV (for an overview see [1]). This corresponds to a total beam power of about 10 kW. After passing of the first dipole primary protons and antiprotons are no longer in-line and the primaries have to be dumped. Behind the target a significant part of the beam power is carried b...

I In this repork we discuss the theory of the "candens& brstory tduique", an approximate mlutioa to the Boltzmam traaqmrt equation that sums tbe dect of up to thousands of d k c t e , small momturn transfer elastic and inch& collisions into single hgert&ct quasitvtnb. Tbis technique saves much ealcdationa1 effort at the expense of introducing errors that arc now understood quantitatirey in term...

The results from a study on the behavior of the GEANT 3.21 Monte Carlo program are presented. The purpose was to study the diierent options available for hadronic interactions, and where possible to compare with data. and ? hadrons were studied at discrete momenta from 100 MeV/c to 1.0 GeV/c. The main conclusion is that the hadronic package currently employed in the CBGEANT Monte Carlo is wrong...
