Development of a low background liquid scintillation counter for a shallow underground laboratory.
Pacific Northwest National Laboratory has recently opened a shallow underground laboratory intended for measurement of low-concentration levels of radioactive isotopes in samples collected from the environment. The development of a low-background liquid scintillation counter is currently underway to further augment the measurement capabilities within this underground laboratory. Liquid scintill...
متن کاملOptimization and Calibration of a Low-background Liquid Scintillation Counter for the Simultaneous Determination of Alpha
The use of low-background liquid scintillation counting (ISC) techniques permits the simultaneous measurement of both alpha and beta emitters with efficiencies close to 100%. In this study, the counting parameters of a Wallac 1220TM Quantulus IS counter have been optimized for the best possible separation of the a and 3 spectra when measuring a sample containing 8 ml of water and 12 ml of Optip...
متن کاملLow Background Liquid Scintillation in Borexino
After a short introduction to solar neutrino physics, this paper describes the design concept and expected performance of the Borexino underground detector at Gran Sasso. Low background results from the Counting Test Facility, the rst phase of the Borexino project, are summarized.
متن کاملDevelopment of High Pressure Xe Scintillation Proportional Counter for Experiments in ”low-background” Physics
Characteristics of a scintillation proportional counter with WLS fiber optics readout is described. The possibility of detection of the proportional scintillation signal produced by the single electron of primary ionization is shown. The counter can be applied for the experiments in ”low–background” physics which require a low energy threshold. E-mail : akimov [email protected]
متن کاملLiquid Helium and Liquid Neon - Sensitive, Low Background Scintillation Media For The Detection Of Low Energy Neutrinos
The use of liquid helium and neon as scintillators for neutrino detection is investigated. Several unique properties of these cryogens make them promising candidates for real-time solar neutrino spectroscopy: large ultraviolet scintillation yields from ionizing radiation, transparency to their own scintillation light, and low levels of radioactive impurities. When neutrinos scatter from electro...
