The detection efficiency of the clover Ge-detectors array at the RITU-GREAT facility
Absolute detection efficiency depending upon its position along the beam line is determined for three germanium detectors, that are part of the GREAT spectrometer at the RITU separator focal plane. The efficiency is determined for an energy range from 80 keV to 1400 keV for all three detectors as an array and also individually using digital electronics. The optimal position for the detector array has been defined for two configurations of the GREAT spectrometer: with planar detector and without it. The obtained results have been compared with three references: a simulation prepared especially for this setup by another student, a previous study that was carried out by applying analogue electronics and a simulation executed during the first years of the GREAT spectrometer operation.

Ion traps in nuclear physics : recent results and achievements
Eronen, Tommi; Kankainen, Anu; Äystö, Juha (Pergamon, 2016)Ion traps offer a way to determine nuclear binding energies through atomic mass measurements with a high accuracy and they are routinely used to provide isotopically or even isomerically pure beams of short-living ions for ... -
Solar neutrino detection in liquid xenon detectors via charged-current scattering to excited states
Haselschwardt, Scott; Lenardo, Brian; Pirinen, Pekka; Suhonen, Jouni (American Physical Society (APS), 2020)We investigate the prospects for real-time detection of solar neutrinos via the charged-current neutrino-nucleus scattering process in liquid xenon time projection chambers. We use a nuclear shell model, benchmarked with ... -
