Failure event and maintenance record based data collection systems have a long tradition in industry. Today, the particle accelerator community does not possess a common platform that permits storing and sharing reliability and availability information in an efficient way. In large accelerator facilities used for fundamental physics research, each machine is unique, the scientific culture, work organization, and management structures are often incompatible with a streamlined industrial approach. Other accelerator facilities enter the area of industrial process improvement, like medical accelerators due to legal requirements and constraints. The Heidelberg Ion Beam Therapy Center is building up a system for reliability and availability analysis, exploring the technical and organizational requirements for a community-wide information system on accelerator system and component reliability and availability. This initiative is part of the EU H2020 project ARIES, started in May 2017. We will present the technical scope of the system that is supposed to access and obtain information specific to reliability statistics in ways not compromising the information suppliers and system producers.

TUBPR03 Major Upgrade of the HIT Accelerator Control System Using PTP and TSN Technology 738

  Two important reasons led to the first developments for a new ACS for the HIT ion therapy accelerator complex: a) the first implementation of the ACS was done in 2003-2005 resulting in well-functioning, but mostly proprietary solutions more and more components of e.g. the specially built device control units (DCUs*) are becoming discontinued, thus a new realization using standard SoCs or similar is necessary; b) new functionality like multiple energy operation** should enhance the duty factor of the accelerator facility resulting in significantly higher patient irradiation efficiency. In cooperation with our commercial partner we are investigating the newly available deterministic Ethernet technologies like "Time-Sensitive Networking" with several IEEE 802.1xx standards. Early TSN implementations in embedded controller boards and switches were obtained in a test installation in autumn of 2018 to study feasibility, e.g. the required timing precision using PTP (resp. IEEE 802.1AS-Rev) to realize a "one-wire-ACS" based on Ethernet only for deterministic data transfer and message based triggers for synchronized ACS functions. We will report on our test bench experiences.
