This is the call for proposals of experiments on materials and life science studies at the RI
Beam Factory (RIBF) of RIKEN Nishina Center for Accelerator-Based Science (RNC).
The Program Advisory Committee for Materials and Life Experiments (ML-PAC) is beingorganized for the evaluation of research proposals in the fields of atomic physics, materials
science, chemistry, biology, and medical research — either new proposals or continuation ones
for on-going experiments — at RNC-RIBF. Please note that due to the closure of the RIKEN
Facility Office at RAL at the end of March 2023, ML-PAC will only accept proposals that use
RIBF.
Some notes for applicants are as follows:(1) We call for proposals of
1. Experiments at the RIBF accelerator facilities,
2. Beam time request for the development of experimental equipments, and3. Construction of large-size instrumentation whose feasibility study has been completed.
Our facilities can be used only for nonmilitary purposes.
