The Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) is establishing an International Monitoring System (IMS) including 80 radionuclide stations, of which 40 will also be equipped with capabilities for measuring CTBT relevant xenon isotopes (Xe-131m, Xe-133, Xe-133m and Xe-135). The CTBTO International Data Centre (IDC) operates dedicated analysis...
Among the most promising technologies for next generation of noble gas systems are those based on Silicon PIN diodes for beta. It has been demonstrated that the high electron energy resolution of these detectors can significantly improve the discrimination power between Xe-131m and Xe-133m. The first next generation noble gas (NG-NG) systems SAUNA-III and SPALAX- NG developed, respectively, by...
The poster briefly describes work using one- and two-dimensional Convolutional Neural Networks (CNNs) to categorize radionuclide spectra. The aim of this work is to automatically recognize 'normal' spectra and thus possibly reduce the work of the human analysts, which would need to focus on the unusual spectra which are more difficult to categorize.
In this study we describe an improved semi-automatic cepstral method for estimating the depth of very shallow earthquakes (depth < 3km ) and explosions. To estimate yield and location, this method is crucial, especially for explosions, for which the depth phase (pP) is not easily discernable from the first arrival (P). Unlike previous cepstral studies, our novel procedure utilizes the Power...
