The IDATEN (International Detector Assembly for fast-Timing measurements of Exotic Nuclei) collaboration has been launched at the RI Beam Factory (RIBF) in the RIKEN Nishina Center (RNC). This project has been realized thanks to the collaboration with FATIMA (FAst TIMing Array) in UK and KHALA (Korea High-resolution Array of LABr3(Ce)) in South Korea. The main body of the IDATEN detector assembly consists of 84 units of cerium-doped lanthanum bromide: LaBr3(Ce) scintillators arising from a combination of 36 FATIMA detectors (Φ1.5”×2”-length crystal each) and 48 KHALA-type detectors (Φ1.5”×1.5”-length crystal each). With this detector configuration, γ-ray full-energy-peak efficiencies of about 20, 9 and 5 % are expected for 100-, 500- and 1000-keV γ rays, respectively. In addition to the LaBr3(Ce) detectors, two Clover-type HPGe detectors will be installed to monitor γ-ray energy spectra with high resolution and to disentangle complex decay spectra by gating on a specific γ ray measured in coincidence with the LaBr3(Ce) detectors. These γ-ray detectors will be arranged around a modified version of the WAS3ABi (Wide-range Active Silicon-Strip Stopper Array for Beta and ion detection) active stopper system, which comprises several layers of double-sided silicon-strip detectors and fast-timing plastic scintillator detectors in a close-packed geometry, at the end of the BigRIPS-ZeroDegree spectrometer (F11). The new IDATEN array has a capability to measure the lifetimes of excited states in the picosecond range by means of electronic fast-timing β-γ and γ-γ coincidence methods.
EURO-LABS is a network of 33 research and academic institutions from 18 countries (25 beneficiaries and 8 associated partners) from European and non-EU countries, involving 47 Research Infrastructures in the Nuclear physics, Accelerators and Detectors pillars. Within this large network, EURO-LABS will ensure diversity and actively support researchers from different nationalities, gender, age, grade, and variety of professional expertise.
The Nuclear Spectroscopy group are leading activities within Service Improvements of Workpackage 2 (Research Infrastructures for Nuclear Physics) in the following topics:
- The INTRANS (INstrumentation and TRAining for Nuclear Spectroscopy and Reaction Dynamics) subtask takes the challenge of providing an expertise on an optimal employment of experimental setups in EURO-LABS for nuclear spectroscopy and nuclear reactions communities. Large research collaborations in those two fields are investing huge efforts and resources in developing new instrumentation (such as, e.g., the AGATA detector array, to name the most challenging one), experimental methods and techniques for front-line research at the different research centres and universities across the world. Most of these techniques are of common interest and the exchange of information as well as the pooling and maintaining of resources will be of great benefit to the whole research community and will lead to enhanced quality and scientific outputs of the experimental programs at the various research facilities. More information can be found in the INTRANS website here.
- The Remote Operations subtask of WP2.5.C1 aims to develop and implement remote-access tools that will be available through a web-based database in order to minimise required access to experimental areas, minimise travel time for on-call experts, maximise external participation and standardise generally-endorsed approaches and procedures.
The objective of the GAMMAPOOL network is to improve the coordination of the European resources used for high-resolution gamma-ray spectroscopy and especially the equipment from the EUROBALL spectrometer including complementary equipment. These resources are available to the European nuclear physics community for experimental campaigns at accelerator laboratories offering unique new physics opportunities.

HiCARI: High-resolution Cluster Array at RIBF
HiCARI (High-resolution Cluster Array at RIBF) is a germanium-based gamma-ray spectrometer composed of MINIBALL, Super Clover detectors and several Ge tracking detectors from Japan, China, South-Korea, Europe and the USA that was used in experimental fast beam campaigns at the RIBF in 2020. More information can be found here.
The high-resolution Miniball germanium detector array has been operational at REX-ISOLDE at CERN for over 10 years, and used in numerous Coulomb-excitation and transfer-reaction experiments with exotic RIBs with energies up to 3 MeV/u, produced at the ISOLDE facility. More information can be found here.
The Nuclear Physics European Collaboration Committee is an Expert Committee of the European Science Foundation. The objective of NuPECC is to:
- develop the strategy for European Collaboration in nuclear science by supporting collaborative ventures between research groups within Europe, and
- promote nuclear physics and its trans-disciplinary use in applications for societal benefit.
