SuN: Summing NaI(Tl) gamma-ray detector for capture reaction measurements
High demand for nuclear reaction cross-section measurements relevant for astrophysical processes requires the development of new experimental techniques that allow for investigation of, often very low, cross-sections. For this purpose, a new 4 pi Summing Nal(Tl) detector (SuN) has been constructed, which is an 8-fold segmented Nal(Tl) barrel read by 24 photomultipliers. The design of the detector will be presented and detailed results of the commissioning experiments utilizing standard calibration sources and known Al-27(p,gamma)Si-28 resonances will be discussed.
