CENTAUR triton-beam workshop at Fox Lab
The CENTAUR workshop serves to discuss the scientific opportunities for experiments with accelerated triton beams, which will become available at the Fox Lab in the near future. The workshop will explore the use of pair-transfer reactions as a tool to extract pairing properties, as surrogate reactions, as a general tool to reach neutron-rich nuclei and other applications. During the workshop, participants will be encouraged to form collaborations around experiments and instruments to help maximize the scientific output of this new and unique capability. Please register here for the workshop.
Particle-gamma coincidences at SE-SPS

CLARION2 installed at FSU
The new CLARION2-TRINITY array was commissioned in December 2021 with a Coulomb-excitation and fusion-evaporation experiment at the John D. Fox Laboratory at Florida State University (FSU). The detector array consists of Compton-suppressed clovers, LaBr/CeBr, a new hybrid charged-particle detector consisting of annular Si and GAGG-SiPM detectors, and a zero-degree detector, which were all installed throughout 2021. Based on community talks and participation in a LECM workshop, the array is anticipated to focus on single- and multi-step Coulomb excitation, stopping powers, Recoil-in-Vacuum calibrations for g factors at FRIB, nucleon transfer reactions, fusion evaporation, and fast-timing measurements.
