STOCKHOLM—In a ceremony this morning that included the prime ministers of both Japan and Sweden, a Memorandum of Collaboration (MoC) was signed between the two Big Science facilities the European Spallation Source (ESS) and the Japan Proton Accelerator Research Complex (J-PARC).
Sweden’s Prime Minister Stefan Löfven and Japanese Prime Minister Shinzō Abe participated in the ceremony, held at Rosenbad, the headquarters of the Swedish government. The Japanese leader is on a two-day visit to discuss innovation and economic cooperation with Sweden. Representing J-PARC was its director Naohito Saito, and Lars Börjesson, Chair of the European Spallation Source ERIC Council, represented ESS. 
“The construction of the European Spallation Source is now one-third complete. As we continue to find solutions to the many challenges of such a large and technically advanced project, the example of our colleagues at J-PARC—who faced similar challenges only a decade ago—will continue to be invaluable,” said Börjesson on the occasion of the signing. “The memorandum signed today confirms what has always been understood: that J-PARC’s cooperation is essential to the success of ESS and the fulfilment of our mission to enable solutions to the great scientific and societal challenges of the 21st century.”

Advancing Spallation Source R&D Worldwide for Neutron Science
The agreement between ESS and J-PARC establishes a framework “to foster research and development for neutron science and technology”. It covers cooperation broadly in such areas as accelerator technology, neutron source development, instrument development, neutron technologies, testing and safety, and includes mechanisms for the transfer of knowledge, technology and staff.
“At J-PARC we operate the world-class neutrino and hadron experimental facilities, along with one of the world’s newest and most powerful spallation sources,” noted Saito, referring to the Materials & Life Science Facility (MLF), which went online in 2009 and is part of the J-PARC complex in Tokai, Japan. “We not only have much to offer our colleagues in recent experience, but much to gain from the cutting-edge developments at ESS. These will inform future upgrades at our own facility. Today’s agreement establishes the way forward for this longstanding cooperation in service to the global neutron science community.”
Saito visited ESS last winter, and led a seminar for ESS management concerning experiences at J-PARC. Also included in the visit was a workshop on the MIRAI initiative, which aims to increase capacity for neutron science through a collaboration between Swedish and Japanese universities. 
J-PARC Experience Critical to ESS Design and Operations
The spallation source at J-PARC has long served as a benchmark for ESS, and the two facilities have been collaborating from the early days of the ESS Design Phase. In April 2015, a joint effort by physicists from the ESS Target Division and J-PARC resulted in a set of experiments at J-PARC that validated the physics behind the breakthrough design of a low-dimensional moderator for ESS. 
“This kind of exchange between world-leading facilities like ESS and J-PARC is an essential ingredient in maintaining research facilities at the cutting edge of performance,” said ESS Director General John Womersley. “It further strengthens the development and utilisation of ESS as the world’s next great Big Science facility.”
More than 40 in-kind partners across Europe will deliver ESS in cooperation with more than 120 institutions worldwide. Once in operation, ESS will serve as a global centre for research with neutrons in fields from engineering to materials and life science. The construction of the facility in Lund, in southern Sweden, is now more than one-third complete, and the transition to initial operations of the facility will start in 2019. 

FAQ About the Arrangement
