The magnetic horn, invented by Simon van der Meer over 50 years ago, has been used in essentially every neutrino beam line since its invention. Analytical calculation and some simulation work has been applied to horn design over the years. In this paper we show how, for the first time, computer-automated horn design optimization can be studied for implementation in a pion beam line like that...

Depending on material, level of energy deposition density and its time structure, one can face a variety of effects in materials under irradiation. Corresponding classes of radiation effects are defined with typical examples given. The dominant mechanism of structural damage of inorganic materials is displacement of atoms from their equilibrium position in a crystalline lattice due to...

The Moliere approximation of elastic Coulomb scattering cross sections plays an important role in accurate description of non-ionization energy, DPA radiation damage etc. The cross section depends only on a single parameter that describes the atomic screening. Moliere calculated the screening angle for the Tomas-Fermi distribution of electrons in atoms. In this report, the screening parameter...

A study of the Energy Production Demonstrator (EPD) concept - a heavy metal target irradiated by GeV-range intense proton beams and its prospective use for the energy production - is carried out. Tungsten, natural uranium, lead, and thorium target options are studied using the MARS15 code. Energy deposition and energy gain, DPA rate and its spatial distribution, materials testing volume,...

The development of the liquid metal spallation target META:LIC (MEgawatt TArget: Lead bIsmuth Cooled) for the European Spallation Source (ESS) at the Karlsruhe Institute of Technology (KIT) is based on previously developed liquid metal targets such as MEGAPIE, MYRHA and IFMIF. Insights gained from the short pulse liquid metal targets at SNS and JSNS lead to increased sensibility towards...

Future perspective for physics measurements at CERN-ISOLDE call for the use of molten metal targets to improve the yield of radioactive isotopes delivered to the experiments and better handle the high power density from the beam. CERN launched in 2012 an R&D project called Liquid Eutectic Lead Bismuth Loop Target for Eurisol (LIEBE) to investigate the feasibility of testing on line a Pb/Bi...

For Chinese-ADS project, the aim is to burn MA. The tens of MW spallation targets for CADS is necessary to provide enough neutron to drive the blanket of MA, which is not an easy task.The first issue of high power target is how to remove the heat by the proton beam of the high current density. For solid targets to be used widely, the heat removal will be limited by the heat conduction of the...
