Neutron scattering and imaging are powerful techniques to study the structure and dynamics of materials over broad time- and length-scales, with applications for studies of materials related to energy & net zero, catalysis, polymer systems, drug delivery, functional materials, magnetism, superconductivity and engineering, amongst many others. Thanks to the strong interaction between neutrons and light elements, these techniques are particularly useful for the study of hydrogen-containing materials like pharmaceuticals or lithium-ion conduction in batteries. The magnetic moment of neutrons also makes them uniquely sensitive to magnetism. 

The ISIS Neutron and Muon Source provides 31 instruments, 27 of which are dedicated to neutron techniques; each year it has 3500 user visits, performs 1000 experiments and produces 600 publications. To harness the capabilities of ISIS for the advancement of Brazilian and UK materials research, and in the wider context of the opportunities offered by the launch of the Brazilian Multipurpose Reactor (RMB) project in Iperó (SP, Brazil), we plan to promote a series of webinars and workshops. In particular, these aim to expand the Brazilian neutron user community by: 


  • Identifying new Brazilian research groups and projects that can benefit from neutron techniques 
  • Training the next generation of researchers in neutron science 
  • Facilitating access to the ISIS Neutron and Muon Source for Brazilian users 
  • Exchanging knowledge on neutron scattering techniques and science 
  • Exploring possibilities for common infrastructure projects for e.g., sample environment development 


The activities and collaborations initiated by the webinars are expected to lead to grant proposals to CNPq/CAPES/FAPESP/STFC to support mobility of scientists for neutron beamtime as well as infrastructure development. 


The first webinar will introduce ISIS Neutron Source and Brazilian funding agencies; the second webinar, hosted by ISIS Staff, will be divided into three broad science areas – Life Science/Soft Matter, Functional Materials, Magnetism/Hard Condensed Matter– and will aim to introduce Brazilian academics unfamiliar with neutron techniques to the underlying principles and applications. These will be followed by another set of three webinars that will provide an opportunity for both experienced and prospective Brazilian neutron users to present their research. It is foreseen that this initial series will start a process that will eventually lead to ISIS beam-time proposal submission in the October 2023 and April 2024 rounds and/or Xpress Access for short experiments to e.g., demonstrate viability ahead of a full proposal. The writing of these beam-time proposals will be supported by ISIS staff, and progress towards obtaining beam-time and new ideas will be discussed at two interim online workshops. Finally, an in-person meeting to discuss initial results and further research plans is foreseen in June 2024. ​
