CAMEA – Continuous Angle Multi-Energy Analysis – An Inelastic Neutron Spectrometer for the European Spallation Source - Final Report

Henrik Moodysson Rønnow, Paul Gregory Freeman

CAMEA is an indirect geometry spectrometer conceived by a Danish (Copenhagen University, Technical University of Denmark) and Swiss (École Polytechnique Fédérale de Lausanne, Paul Scherrer Insitut) Collaboration for the European Spallation Source (ESS), Lu ...

Embrittlement induced by the synergistic effects of radiation damage and helium in structural steels

Kun Wang

Ferritic/martensitic steels are candidate materials for fusion reactor structural components, liquid metal containers of spallation neutron sources, and accelerator driven systems, with good radiation resistance and thermo-mechanical properties. However, e ...

Energy-selective neutron imaging for materials science

Steven Luc X Peetermans

Common neutron imaging techniques study the attenuation of a neutron beam penetrating a sample of interest. The recorded radiograph shows a contrast depending on traversed material and its thickness. Tomography allows separating both and obtaining 3D spati ...

A locally calibrated, late glacial 10Be production rate from a low-latitude, high-altitude site in the Peruvian Andes

Katherine Colby Leonard

Well-dated records of tropical glacier fluctuations are essential for developing hypotheses and testing proposed mechanisms for past climate changes. Since organic material for radiocarbon dating is typically scarce in low-latitude, high-altitude environme ...

Continuous Angular Multiple Energy Analysis Spectrometer Report on Instrument Concept and Scientific Case

Paul Gregory Freeman

Abstract This work unit proposes to construct a cold indirect geometry time of flight spectrometer for performing inelastic neutron scattering experiments optimized for optimal efficiency in the horizontal scattering plane at the European Spallation Source ...

Simulation of a suite of generic long-pulse neutron instruments to optimize the time structure of the European Spallation Source

We here describe the result of simulations of 15 generic neutron instruments for the long-pulsed European Spallation Source. All instruments have been simulated for 20 different settings of the source time structure, corresponding to pulse lengths between ...

An experiment to test advanced materials impacted by intense proton pulses at CERN HiRadMat facility

Nikolaos Charitonidis, Francesco Cerutti, Alessandro Masi

Predicting the consequences of highly energetic particle beams impacting protection devices as collimators or high power target stations is a fundamental issue in the design of state-of-the-art facilities for high-energy particle physics. These complex dyn ...

Investigation of liquid LBE embrittlement effects on irradiated ferritic/martensitic steels by slow-strain-rate tensile tests

Nadine Baluc, Yong Dai

In the present work, LBE (lead-bismuth eutectic) embrittlement effects on ferritic/martensitic (FM) steels have been studied by conducting slow-strain-rate tensile (SSRT) testing on T91 and F82H steels either in Ar or in liquid LBE after irradiation to dos ...

Characterization of Extended Range Bonner Sphere Spctrometers in the CERF high-energy broad neutron field at CERN

Nikolaos Charitonidis, Angelo Esposito, Marco Silari

The accurate determination of the ambient dose equivalent in the mixed neutron-photon fields encountered around high-energy particle accelerators still represents a challenging task. The main complexity arises from the extreme variability of the neutron en ...

Helium-induced hardening effect in ferritic/martensitic steels F82H and Optimax-A irradiated in a mixed spectrum of high energy protons and spallation neutrons

Yong Dai

Ferritic/martensitic (FM) steels, F82H and Optimax-A, were irradiated up to 11.3 dpa/1175 appm He in Target-3 of the Swiss Spallation Neutron Source (SINQ). To investigate helium-induced hardening effect, micro-hardness and microstructure of the irradiated ...
