ECNS 2019: a very successful conference!

An impression of the Saint Petersburg ECNS 2019 conference: the marvelous conference venue MANEGE CENTRAL EXHIBITION HALL in the center of St Petersburg, next to the St. Isaac Cathedral; the opening session on Sunday afternoon by the officials; the 25th celebration of ENSA, celebrated with the user community and a beautiful cake and concert, which were generously offered by the local ECNS organisers: many thanks!

First Instrumentation & Innovation Prize

The winner of the inaugural 2019 ENSA Neutron Instrumentation and Innovation Award is Markus Appel.

“For ground-breaking advances of the neutron back-scattering technique leading to extended dynamic range, higher resolution and better signal-to-noise on the IN16B spectrometer at ILL”.

Markus Appel, currently a staff scientist at ILL, has since his PhD from TU Darmstadt devoted his talents to implementing innovative improvements to the neutron backscattering technique. These span from conceptual changes such as moving from monochromator to time-of-flight, over clever rephrasing of choppers to achieve ultra-low background, to the material and mechanical challenge of implementing GaAs analyzers. Together these improvements to the IN16B spectrometer at ILL has enabled a wide range of exciting science by a large number of user groups – perfectly embellishing the spirit of the Neutron Instrumentation and Innovation Award. More information about the award, sponsored by Mirrotron, can be found here (

Work in progress

The previous ENSA website has been blocked for some time now, due to technical problems. We are constructing a new site at this moment. Please bear with us.

Hello Neutron Scatterers!

Welcome to the new website of the European Neutron Scattering Association (ENSA).

We, ENSA, represent the scientists that use large-scale research infrastructures that operate a neutron source, like research reactors and accelerator-based spallation sources.

Half of the worlds mass actually consists of neutrons. Half of you consists of neutrons. Neutrons bind together the protons in the core of atoms, and therefore make atoms possible, and the world as we know it!

As scientists we like to liberate such neutrons from atom cores, just because they are such great probes for investigating matter, physics, chemistry and biology. To liberate enough neutrons from atoms, one requires big scientific infrastructures (big, as in not being table-top equipment). ENSA is the pan-European representation of scientist that visit such infrastructures to perform their experiments.
