[en] To build and strengthen its relationship with the broader science community in support of the Treaty, the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) invites the community to a scientific conference CTBT: Science and Technology 2011 (S and T 2011), to be held from 8 to 10 June 2011 at the Hofburg Palace in Vienna, Austria. The conference goals are: Discuss advances in science and technology relevant to test ban verification; Explore scientific applications of the CTBT verification infrastructure; Encourage partnerships and knowledge exchange between the CTBTO and the broader scientific community.
[en] This document contains the system specifications derived to satisfy the system requirements found in the IDC System Requirements Document for the IDC Re-Engineering Phase 2 project. This System Specification Document (SSD) defines waveform data processing requirements for the International Data Centre (IDC) of the Comprehensive Nuclear Test Ban Treaty Organization (CTBTO). The routine processing includes characterization of events with the objective of screening out events considered to be consistent with natural phenomena or non-nuclear, man-made phenomena. This document does not address requirements concerning acquisition, processing and analysis of radionuclide data but does include requirements for the dissemination of radionuclide data and products.
[en] This presentation briefly describes the Zambian Seisimic Network (ZSN), Zambia's participation in past CTBTO activities and upgrading of AS119 and N192. It goes on to describe various experiences encountered and makes some suggestions for future considerations
[en] This report is divided into the following 5 sections: (1) Background; (2) Major Issues Facing Ratification of CTBT; (3) Current Status on CTBT Ratification; (4) Status of CTBT Signatories and Ratifiers; and (5) CTBT Activities Not Prohibited. The major issues facing ratification of CTBT discussed here are: impact on CTBT of START II and ABM ratification; impact of India and Pakistan nuclear tests; CTBT entry into force; and establishment of the Comprehensive Nuclear Test-Ban Treaty Organization
[en] The document gives information about the Hiroshima-Nagasaki exhibition organized by the two cities together with IAEA, CTBTO and UN Office in Vienna in September 2000 at the Vienna International Centre, with the occasion of the fifty-fifth anniversary of the dropping of the atomic bombs on these cities
[en] The Comprehensive Nuclear-Test-Ban Treaty (CTBT) bans nuclear explosions by everyone and everywhere in the atmosphere, underwater and underground. In preparation for entry into force of the Treaty, the Preparatory Commission for the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) has been tasked to establish the International Monitoring System (IMS) to monitor the planet for signs of nuclear explosions. The IMS consists of 321 globally distributed monitoring stations that continuously provide in near real-time measurements of seismic, infrasound, hydroacoustic and radioactivity sensors. The five announced nuclear tests of the Democratic People's Republic of Korea have all been detected and this demonstrates the effectiveness of the monitoring system. The CTBTO maintains close cooperation with the scientific community to constantly refine its methods and ensure that the verification regime operates at the cutting edge of scientific knowledge. This presentation describes the science and technology process and uses the area of radionuclide analysis as an example how processing and interpretation of IMS data is improved by research and methodology developments. Global efforts are undertaken to understand the radioxenon background in the atmosphere that results from civil sources, to characterize the observations at IMS noble gas systems and to screen them for possible indications of signals that may be caused by a nuclear explosion so as to optimize the detectability of nuclear tests.
