A New ITPA Disruption Database
Abstract
A new multi-institutional database of tokamak disruption relevant information is being proposed. Its purpose is to allow a user at any participating institution access to a broad range of disruption and preceding equilibrium data of vetted discharges from each institution. The goal is a common set of data allowing scientific exploration and engineering extrapolation. The data for any given discharge can be in many forms. For example, each discharge may have identifying information (shot number, type of disruption, institution/device, etc.), equilibrium scalar parameters (β, I_p, B_tor, etc.), disruption scalar parameters (max dI/dt, thermal quench time, toroidal asymmetry, etc.), equilibrium radial profile data [j(r), p(r), v_rot(r), etc.], time sequenced data [I(t), β(t), precursor amplitude (t), etc.]. Scalar data will be stored in a SQL format and cross-linked with vector data stored in a MDSPLUS format. Institutions will populate and maintain their own disruption data. Data visualization and analysis tools will be developed. Data available to all is managed by a principal at each institution. Data structure, accessibility and security issues will be discussed, and participation solicited.
