ESS Science Symposium on Neutron Particle Physics at Long Pulse Spallation Sources

25 - 27 March, 2013

English French Deutsch 

Press and news


The symposium discussed particle physics using neutrons at long-pulse spallation sources. Topics are:

  • Application of neutrons in particle physics in 10 years from now (scientific case)
  • Concepts and needs for instrumentation, including UCN sources, at the ESS. Of particular interest are concepts that profit from specific properties of a long-pulse spallation source (time structure, flexibility of moderators...)

The symposium consisted of invited and contributed talks, with ample time for discussions.

The main aim was to identify the needs of the neutron particle physics community at the ESS. The results of the workshop will be presented to the ESS in a written document.

In order to keep the discussions efficient, the number of participants was limited to 50. (Muon or neutrino applications were not covered)

Dates and place

The workshop took place from 25 March to 27 March, 2013 at the LPSC, Grenoble, France.
The LPSC (Laboratoire de Physique Subatomique et de Cosmologie) is located on the Polygone Scientifique, close to the ILL (Institut Laue Langevin).

The design update of the European Spallation Source (ESS, in Lund, Sweden, is progressing. The ESS will be a long-pulse spallation source with a time-averaged flux comparable to that of the ILL. Thus it will provide unique opportunities for neutron users. In order to involve the user community in the selection and design of instruments, the ESS is funding Science Symposiums that discuss the requirements of specific user communities.
