Due to high neutron and gamma-ray yields and large size plasmas many future fusion reactor plasma parameters such as fusion power, fusion power density, ion temperature, fuel mixture, fast ion energy and spatial distributions can be well measured by various fusion product diagnostics. Neutron diagnostics provide information on fusion reaction rate,…

Achieving the economically viable release of energy by the fusion process has proved a major scientific and technological challenge. The nuclear reactions involved in the fusion process are well understood, but the interaction of the neutrons with the materials surrounding the plasma is an area of current research. The neutrons have energies larger…

Throughout the various phases of the ITER project, extensive safety analyses have been performed to ensure that potential hazards to the public, the environment, and personnel are minimized. This work, done before a location for ITER had been chosen, resulted in a very comprehensive assessment of ITER safety in terms of the impact at a “generic s…

The technology underlying a ceramic capacitive diaphragm gauge CDG manometer has been investigated for use as a microbalance for measurement of dust accumulation in next-step fusion devices such as ITER. Initial trials have confirmed in principle the use of CDG devices as dust microbalances and both the gauge head and electronics have been adapted …

Laboratory experiment is an attractive method of exploring the plasma physics that may occur in solar and astrophysical shocks. An experiment enables repeated and detailed measurements of a plasma as the input conditions are adjusted. To form a scaled experiment of an astrophysical shock a plasma physics model of the shock is required, and the impo…
