Deep geologic repository progress—2025 Update
Editor's note: This article has was originally published in November 2023. It has been updated with new information as of June 2025.
Outside my office, there is a display case filled with rock samples from all over the world. It contains a disk of translucent, orange salt from the Waste Isolation Pilot Plant near Carlsbad, N.M.; a core of white-and-bronze gneiss from the site of the future deep geologic repository in Eurajoki, Finland; several angular chunks of fine-grained, gray claystone from the underground research laboratory at Bure, France; and a piece of coarse-grained granite from the underground research tunnel in Daejeon, South Korea.

The poloidal field (PF) power supply is an important subsystem of the Experimental Advanced Superconducting Tokamak (EAST). The monitor system of the PF power supply is based on the Experimental Physics and Industrial Control System (EPICS), using Control System Studio (CSS) as the human-machine interface. Archive, which is for data archiving, is a plugin of CSS. This paper creates an archiving system, including archive engine, client, and relational database (RDB). The process variables that need to be archived are configured so that they can be stored to RDB when changed. Real-time archiving for all input signals is realized, and history data can be browsed at any time through CSS. The archiving system provides a data basis for analyzing the EAST PF power supply, applied to the EAST experiment for more than 5 years, showing stable performance.
