Poster for first Brazilian Neutron User Meeting, 26-28 Jan 2026, IPEN, Sao Paulo.

​​This is a collaboration between ISIS Neutron and Muon Source (United Kingdom) and Brazilian Multipurpose Reactor (RMB).

Recent collaboration between ISIS and Brazilian researchers has been supported by an award from the UK Internatio​nal Science Partnerships Fund (ISPF), from 2023 to 2027. Activities have included neutron training courses, webinars and, most importantly, the Brazilian Access to ISIS instruments  for a wide range of materials studies. Up to the beginning of 2026, ISPF will have granted around 40 beamtimes for Brazilian Access, covering the costs of around 80 Brazilian research scientists coming to ISIS. ISIS has recently signed a collaboration agreement with Comissao Nacional de Energia Nuclear (CNEN) in Brazil, and welcomed RMB visitors in July 2025.

The ISIS Neutron and Muon Source provides 35 instruments for neutron and muon techniques and each year has around 3500 user visits, 1000 experiments producing 600 publications. In view of the upcoming opportunities offered by the launch of the Brazilian Multipurpose Reactor (RMB) project, we propose to have this first neutron user meeting at IPEN, where the Brazilians, who had neutron beamtime at ISIS, or anywhere else, could present their projects and meet other Brazilian researchers working in areas where neutrons could be applied in the future. ​

There is no registration fee and we are still looking for resources to be able to invite some participants not coming from Sao Paulo state. We strongly encourage you all to request funds from your own end to cover for transport and accommodation.
