Oasis-an innovative system for alpha spectroscopy

Until recently, instrumental alpha spectroscopy has behind the technical developments of instrumentation and software that are available for low background o c/ counting, liquid scintillation, and gamma spectroscopy instruments. We report in this paper, the development of Oasis, a new family of alpha spectroscopy systems from oxford instruments Inc., Nuclear measurements Group. The Oasis instruments incorporate many hardware and software innovations providing an automated and integrated production environment for alpha spectroscopy. These instruments are needed because of the large number of samples to be measured and the required throughput of production laboratories processing these samples. Oasis is also useful for facilities because of their sophisticated vacuum control, management, and analysis features. One of the most important innovations is the electronic vacuum system and cartesian diver. Many additional features contribute to improving accuracy, lowering cost per sample, improving sample throughput, and ensuring accountability of laboratory results. 5 figs
