A very special instrument was set up at GSI/FAIR: The WASA detector. Together with the fragment separator FRS, it will be used to produce and study so-called hypernuclei which play an important role for processes in neutron stars. For this purpose, the assembly, which weighs several tons, is being transferred to the facility in a complex installation procedure.
Hypernuclei
Regular atomic nuclei are made of protons and neutrons, which in turn are composed of a total of three up and down quarks. If one of these quarks is replaced by another type, a so-called strange quark, a hyperon is formed. Atomic nuclei that contain one or more hyperons are called hypernuclei. They can be produced in particle collisions at accelerators, and their decay can then be observed in experiment setups such as the WASA detector and the FRS in order to study their properties in detail.
Professor Takehiko Saito, leading scientist in the GSI/FAIR research pillar NUSTAR: “Hypernuclei could shed light on what happens inside neutron stars. According to current predictions, hypernuclei should exist there abundantly. However, some of their properties have not yet been accurately determined. Among other things, the researchers want to determine the binding energy and lifetimes of different hypernuclei more precisely in future experiments, as well as discover new variations."
