Materials R&D for a timely DEMO: Key findings and recommendations of the EU Roadmap Materials Assessment Group

Minh Quang Tran

The findings of the EU Fusion Programme's 'Materials Assessment Group' (MAG), assessing readiness of Structural, Plasma Facing (PF) and High Heat Flux (HHF) materials for DEMO, are discussed. These are incorporated into the EU Fusion Power Roadmap [1] , wi ...

Cold neutron diffraction contrast tomography of polycrystalline material

Steven Luc X Peetermans, Andrew King

Traditional neutron imaging is based on the attenuation of a neutron beam through scatteririg and absorption upon traversing a sample of interest. It offers insight into the sample's material distribution at high spatial resolution in a non-destructive way ...

Evaluation of two thermal neutron detection units consisting of ZnS/(LiF)-Li-6 scintillating layers with embedded WLS fibers read out with a SiPM

Helena Van Swygenhoven

Two single channel detection units for thermal neutron detection are investigated in a neutron beam. They consist of two ZnS/(LiF)-Li-6 scintillating layers sandwiching an array of WLS fibers. The pattern of these units can be repeated laterally and vertic ...

Instrument intercomparison in the pulsed neutron fieldsat the CERN HiRadMat facility

Nikolaos Charitonidis, Daniel Perrin

An intercomparison of the performances of active neutron detectors was carried out in pulsed neutron fields in the new HiRadMat facility at CERN. Five detectors were employed: four of them (two ionization chambers and two rem counters) are routinely employ ...

Equation of state of lead from high-pressure neutron diffraction up to 8.9 GPa and its implication for the NaCl pressure scale

Jonathan White

From high-resolution neutron-diffraction experiments we present equation-of-state (EOS) data of elemental lead as functions of both temperature (80-298 K) and applied pressure (up to 8.9 GPa), with the pressure values derived from the NaCl pressure gauge. ...

Miniature Fission Chambers Calibration in Pulse Mode: Interlaboratory Comparison at the SCK·CEN BR1 and CEA CALIBAN Reactors

Vincent Pierre Lamirand

Miniature fission chambers are suited tools for instrumenting experimental reactors, allowing online and in-core neutron measurements of quantities such as fission rates or reactor power. A new set of such detectors was produced by CEA to be used during th ...

VERIFICATION OF A REACTOR PHYSICS CALCULATION SCHEME FOR THE CROCUS REACTOR

Andreas Pautz, Mathieu Hursin, Daniel Jerôme Siefman, Adolfo Rais, Gaëtan Girardin

CROCUS is a zero power (100 W) reactor of the Laboratory for Reactor Physics and Systems Behavior (LRS) at the Swiss Federal Institute of Technology, Lausanne (EPFL). It is used for teaching and research purposes. Its modeling has relied so far on diffusio ...

Definition of the radiation fields for the JET gamma-ray spectrometer diagnostics

Patrick Blanchard

The JET gamma-ray diagnostics system provides information on the behaviour of fast particles within the tokamak plasma. Information on the spatial distribution of the interacting fast particles is obtained from the gamma-ray cameras, while energy distribut ...
