workshop on instruments for ESS
Scope of the workshop
ESS reference design was presented on the occasion of the Bonn meeting
in 2002. Since then, the
SNS has produced its first neutron pulses and the Japanese JPARC
project has moved ahead and will create first neutron beams in
the European front, the European Strategy Forum on Research
Infrastructures (ESFRI) has prepared a document reviewing the
challenges, risks and returns of competitive large scale Research
Facilities for Europe. In particular, in the field of Material
Sciences, ESFRI has recognized that the European leadership in neutrons
is now decreasing and has proposed that the European Spallation Source
(ESS) be a high priority for Europe. ESFRI has also recommended to
“upgrade the instruments suite of the international source ILL”.
The original ESS design contained two target stations: a long pulse
(LP) station and a short
pulse (SP) station, to be fed by the same accelerator.
The European Spallation Source
Initiative has decided that the ESS should initially be a 5 MW LP
facility, upgradeable to more instruments, more power and more target
stations. ESFRI has endorsed this choice. Initiatives from several
European governments have recently indicated willingness to host the
ESS. For the start of formal negotiations it is important to consider
again the list of neutron instruments which
would benefit most from the neutron beams produced by a 5MW LP target
this context we are bringing together neutron instrument experts and
instrument modelers to discuss and assess potential gains expected
from the ESS LP target station with respect to existing neutron
sources. It is the purpose of this workshop to propose a list of
day-one neutron scattering instruments to be built at the LP-ESS which
would could meet the needs of European scientists.
with existing European sources will be considered in order to offer an
optimized suite of neutron facilities to the scientific community. The
workshop report will serve as a technical basis document for further
discussions at the European level. It is intended to make this document
available to the neutron users community in Europe through publication
in a scientific journal.
Aims of the workshop
- Summarize previous studies
- Identify relevant parameters
- Improve instrument designs (flux, resolution, etc...) based on
discussions, analytical estimates and simulations.
- Write documentation as a journal paper (for Neutron News, NIMA
...). This document should be nearly ready at the end of the workshop.
