KoBRA and 40Ar9+ beam commissioning
摘要
The apparatus (KoBRA) was recently constructed at the Institute for Rare Isotope Science (IRIS). In 2023, an 40Ar9+ beam from the electron cyclotron resonance (ECR) ion source was transmitted to the KoBRA, and a carbon graphite target was used to successfully produce and separate several isotopes. In this paper, we will report on the results of the first beam commissioning experiment, as well as the beamline detectors and data acquisition (DAQ) system. Additionally, we will discuss the upgrades to the detection system for the installation of user detection systems.
