Implementation and Technical Evaluation of Shot-by-Shot Data Transfer from GAMMA 10/PDX To LHD LABCOM Via SNET

Year: 2025

Type: article

Abstract: We report the implementation and technical evaluation of a shot-by-shot data transfer system from the GAMMA 10/PDX tandem mirror device to the LHD LABCOM system via SNET, as part of the Fusion Virtual Laboratory project. Since 2008, we have transferred approximately 1.5 TB of experimental data annually. In 2023, we successfully established real-time CAMAC data transfer on a per-shot basis. This paper details the network architecture, data acquisition systems, transfer protocols, and operational reliability. The system enables remote access and supports collaborative research by providing timely and structured data to the LABCOM database. The technical performance and future development plans are also discussed.
