3rd Joint Workshop of RIKEN RAP and JCNS

18 March 2019

The Japanese RIKEN Center for Advanced Photonics (RAP) and the Jülich Centre for Neutron Science (JCNS) held their third joint workshop on compact accelerator-driven neutron sources (CANS) on 21 February at RIKEN RAP. The workshop tackled common research topics regarding the development of target and moderator systems for CANS at both institutes. It was organized in conjunction with the annual RIKEN Symposium which was focused on “Compact neutron source RANS and RANS II for a safe and secure society” held on 20 February at RIKEN.

JCNS: “High Brilliance Neutron Source” Workshop

23 October 2018

From 4-5 October, 2018, the fourth international workshop on High Brilliance Neutron Sources based on a compact accelerator system was held in Unkel, Germany. Organized by the Jülich Centre for Neutron Science (JCNS), the workshop was attended by more than 30 experts from France, Hungary, Italy, Japan, Spain, Switzerland, Sweden and Germany. They were welcomed by Prof. Thomas Brückel, director at JCNS, who gave an overview of previous meetings and the significant progress which has already been made to develop compact and high brilliance neutron sources over the last few years.

NOVA ERA Conceptual Design Report available

The conceptual design of a versatile small compact accelerator based neutron source for science, education and industry has been compiled and published by the HBS project.

The new concept of a small neutron source named NOVA ERA (Neutrons Obtained Via Accelerator for Education and Research Activities) describes a small 400 W average power neutron source based on a commercial electrostatic tandetron. It aims to perform basic experiments with neutrons at universities, research institutes and industry laboratories (see right for more details).

HBS Science Case Workshop 2017

6-7 April 2017

More than 30 experts from Spain, Italy, Switzerland, Hungary, England, France, and Denmark joined the HBS Science Case Workshop organized by the Jülich Centre for Neutron Science (JCNS) on 6-7 April, 2017 in Unkle, Germany. The resulting Science Case will be published as part of the forthcoming conceptual design report (CDR) for the high brilliance accelerator-driven neutron source planned by JCNS.

HBS-Workshop 2016

29-30 September 2016

An international workshop on the topic of accelerator based high brilliance neutron sources took place in Unkel, Cologne area, in Germany on Sept. 29-30. The workshop was the second workshop of this kind and organized by the Jülich Centre for Neutron Science (JCNS). The workshop covered the latest developments in the area of targets, moderators, beam extraction, beam guidance and neutron optics, which will make the realization of an extremely compact neutron source possible, with accelerators of relative low final particle energy.

Press Release: Forschungszentrum Jülich Plans Novel Neutron Source

17 February 2016

Research with neutrons offers unique insights into the internal structure of matter, making it a key technology for many areas of science. These complex studies are often undertaken at research reactors, many of which will reach the end of their operational life in the coming years. Forschungszentrum Jülich has begun to develop a concept for cost-efficient neutron sources which coud replace mid-sized facilities.

The new sources will operate without using reactor-typical chain reactions. Even smaller facilities on a laboratory scale can be set up using the same principle.

Scientists presented the concept and the results of the first component tests in the January edition of the international journal European Physics Journal Plus (DOI: 10.1140/epjp/i2016-16019-5) and at the tenth anniversary celebrations of the Jülich Centre for Neutron Science (JCNS) on 17 February.
