Réactions secondaires de spallation

Nuclear Physics, 1960
Abstract In the spallation nuclear reactions induced by 150 MeV protons om bismuth and thallium, light fragments are produced. Alpha particles induce secondary reactions. By radio-chemical study of astatine isotopes, cross sections for (α,2n) to (α,6n) reactions are measured.

Spallation neutron source GNEIS

Physics of Particles and Nuclei, 2018
A brief description of the spallation pulsed neutron source and neutron TOF spectrometer GNEIS based on the 1 GeV proton synchrocyclotron of PNPI in Gatchina is presented. The main parameters of the GNEIS are given in comparison with the analogous world-class facilities.

The European Spallation Source

2013 IEEE 14th International Vacuum Electronics Conference (IVEC), 2013
The European Spallation Source (ESS) requires 5 MW of proton beam power which is a factor of five larger in power compared to existing spallation facilities. To accommodate the high power, the ESS facility will pioneer the long pulse concept. The proton linac sourcing the neutron spallation target will be a 2 GeV superconducting linac that requires 125

Measuring Spallation Strength of Epoxy by Laser Spallation Technique

The laser spallation technique in combination with Michelson interferometry is employed to estimate the spallation strength of epoxy film. The epoxy layer of thickness 160 μm is deposited onto the microscopic glass (MG) substrate. The specimens are subjected to high amplitude short duration stress waves, developed by the pulsed laser ablation of ...

The European spallation source

Applied Physics A: Materials Science & Processing, 2002
This article surveys the present status of the European spallation source (ESS). Starting with an account of the ESS feasibility study, the ESS project development until summer 2001 is briefly described. Particular emphasis is placed on the recent science-driven target station evaluation, leading to the choice of a long-pulse 16\(\frac\Box2\Box\Box3 ...

Spallation of light nuclei

Nuclear Physics A, 1967
Abstract The experimental data on proton and neutron spallation of light nuclei (9 ≦ A ≦ 32) have been gathered and analysed. The important features are made quantitative interms of certain parameters, similar, (but not identical) to those used by Rudstam1,2) to study heavier nuclei (A>40).

Japanese spallation neutron source

Applied Physics A: Materials Science & Processing, 2002
The Japanese ‘Joint Project’ is a new project to pursue frontiers in particle physics, nuclear physics, materials science, life science and nuclear technology, using a new proton-accelerator complex with the highest beam power in the world. This project had been jointly proposed by the High Energy Accelerator Research Organization (KEK) and the Japan ...

Long pulse spallation sources

Physica B: Condensed Matter, 1997
Abstract Design considerations for new spallation source projects have to involve a global optimisation of the whole accelerator-target stations-instrument suite ensemble. One particular aspect of this process is concerned with the fact that compared to a linac plus storage ring or synchrotron configuration, a given proton beam power can be achieved ...
