Description
The Joint European Torus (JET) has produced over 1PB of raw and processed data over its 40-year lifetime. Raw data is stored in a proprietary data format which varies depending on the underlying experimental source. The legacy nature of this format and the associated software poses some challenges for both adding new sources and considering the long-term preservation of the data and metadata. I will discuss the technical solutions which attempt to address these challenges at opposite ends of the data lifecycle, and describe how they apply both during JET’s operational life and when operations finish at the end of 2023. This includes migrating the data to a new location separate from its original infrastructure, handling emerging techniques for data analysis, and preparing raw data for long term maintainability. Additionally, I will draw comparison with new approaches to making data from the Mega Ampere Spherical Tokamak (MAST) fusion experiment accessible.
