First experiments of the R3B collaboration at FAIR
"Following the preparation work in 2018, the R3B collaboration, in which LIP participates, recently executed the first series of experiments, part of the so-called "Day-0" at FAIR, GSI."
Following the preparation works done during 2018, the R3B (Reactions with Relativistic Radioactive Beams) collaboration at the FAIR (Facility for Antiproton and Ion Research) laboratory executed, during the past February, the first series of experiments that constitute the so-called Day-0 experiments at FAIR.
The first run, under the acronym S444, consisted in the joint commissioning of the new detection systems that had been developed over the past ten years, and will give shape to the R3B experiment. Among them we could find a large portion of the future calorimeter CALIFA (CALorimeter for In-Flight detection of gamma rays and high energy charged pArticles), a scintillation based detector that will act simultaneously as photon spectrometer and light charged particle identifier.
Members of the NUC-RIA group from LIP joined the preparation and execution phases of the experiment, with a strong focus on the development of data analysis and calibration tools related to CALIFA.
