Precalibrated Ion Beam Identification Detector
[Examensarbete för kandidatexamen]
When conducting experiments with radioactive beams, a recurring problem is to iden- tify the ions occurring in the beam. The identification process makes use of different detectors, which must be calibrated prior to usage — a process often requiring beam. This project investigates a concept and design for a help detector that can be calibrated without beam access. This pre-calibrated detector is to be used at the initial calibration of other detectors in the experimental setup, in order to save expensive beam time. The calibration in question is performed by, in turn, making absolute identifications of indi- vidual ions that have been detected by the main experimental setup. This identification is done by utilizing coincidence between β- and γ-decays in the detector and comparing measured γ-energies with tabulated values.
