Research strategy with open-closed data utilization in nuclear
physics experiments
H. Baba∗1
A workshop on Research strategy with open-closed
data utilization in nuclear physics experiments1) was
held on March 7th, 2022 at Integrated Innovation
Building of RIKEN Kobe campus in a hybrid format
with both on-site and remote participation. This workshop was supported by RIKEN’s internal fund dedicated to data utilization promotion support.
Open science and open data schemes are currently
being attempted worldwide. RIKEN has also been promoting open science especially in the ﬁelds of life andmedical science.2) For example, in accelerator based
sciences, some particle physics experimental data areopened at CERN.3) Even in open science approaches, it
is recommended that open-closed data be strategicallyselected, rather than all data being open. For example,
regarding satellite data for astronomy, for which open
access is common, the spokesperson is often given a
period of several years of occupied use. This workshop
was held to discuss “What kind of demands and effects can be expected by open data of nuclear physics
experiments at RIBF?.”
There were 19 participants from RIKEN Nishina
Center, RIKEN Information R&D and Strategy Headquarters, Japan Atomic Energy Agency, Hokkaido University, Konan University, Kyoto University, Kyushu
University, Research Center for Nuclear Physics, Osaka University, University of Miyazaki, University ofTsukuba, Tohoku University, Tokyo City University,
and Yokohama National University. 9 regular talks
and 8 short talks were presented:• Background and purpose of this workshop• RIKEN’s open science initiatives for maximizingresearch results• Activities on nuclear data
• Past nuclear data research activities and latest initiatives• Suggestions from the nuclear engineering community regarding RIBF data
• Suggestions from theoretical studies regarding
RIBF data• Research and education at the University ofMiyazaki• Research and education at Tokyo City University• Current status and future of research and education at Konan University• Comments from Nishina Center Promotion Oﬃce(short talk)• Comments from Tohoku University (short talk)• Comments from Kyoto University (short talk)∗1RIKEN Nishina Center- 217 -• Comments from Research Center for Nuclear
Physics, Osaka University (short talk)• Comments from RIKEN Slow RI Data Team(short talk)• Comments from RIKEN Radioactive Isotope
Physics Laboratory (short talk)• Comments from experimentalist of RIBF User Executive Committee (short talk)• Comments from theorist of RIBF User Executive
Committee (short talk).
As a result of active discussion, several initiatives
were proposed.
1) A detailed database of experiments conducted atRIBF: make a table of nuclei, energies, targets, measured quantities of approved experiments at RIBF tounderstand what kind of experiments are planned.
2) RIBF experiments assuming data sharing : try toshare not only data but also analysis methods to accumulate knowledge and experience as a software library.
3) Registration to nuclear data: not all RIBF experimental results will be registered, especially those of
master’s thesis. We will continue to discuss methodsof registration.
We are continuing our discussions on how to realize
open-closed data in the nuclear ﬁeld, starting from thisworkshop.
