Gamma and conversion electron spectroscopy using GABRIELA

Abstract: GABRIELA (Gamma Alpha Beta Recoil Investigations with the Electromagnetic Analyzer) is a detection system installed at the focal plane of the SHELS (Separator for Heavy Elements Spectroscopy) recoil separator for gamma and internal conversion electron spectroscopy of heavy and superheavy nuclei. GABRIELA has recently been upgraded. The characteristics of the new setup are presented using the Geant4 Monte Carlo simulation toolkit and validated against experimental results. The impact of summing on the gamma-ray… Show more

“…All the germanium detectors are surrounded by 15 mm thick BGO Comptonsuppression shields in order to reduce the rate of background events and to improve the peak-to-total. The detection efficiency of γ rays is ∼10% at 600 keV and peaks at ∼30% for photon energies around 100 keV [5].…”

“…The average energy of the beam was 244 MeV. The separator for heavy element spectroscopy (SHELS) [7] was used to select the evaporation residues of interest and the newly upgraded GABRIELA detector array [8,9] was used to detect the residues and their subsequent α decay or fission as well as γ and X rays and conversion electrons. After selection in SHELS, the evaporation residues of interest pass through a Time of Flight (ToF) detector and are then implanted into a 10×10 cm 2 500 µm thick Double-sided Silicon Strip Detector (DSSD).…”

“…The nuclei of interest were separated by SHELS and implanted into the 10x10 cm 2 Double Sided Silicon-strip Detector (DSSD) of the newly upgraded GABRIELA detector array [4]. This detector provides 16384 different pixels for genetic position and time correlations between implantation and subsequent decay events.…”
