Conceptual reasoning in the development of particle accelerator control systems: A case study on controls for a novel accelerator design

This paper explores the relevance of certain semiformal communication (we call “Conceptual Reasoning”) in the controls and computing systems development at particle accelerator research facilities, and promotes its facilitation in the domain. The chosen research methodology approach is based on participatory research and intervention in a real engineering environment. An introduction to the concept of viewpoints in Systems Engineering literature is given. The idea of Conceptual Reasoning, which constitutes a practical mean of integrating different viewpoints, is explained. The relevance of Conceptual Reasoning in the development of particle accelerator based research facilities is outlined based on the characteristic properties of this type of engineering environment. A case study on Conceptual Reasoning in the domain is described, exemplified in more detail for the controls of a novel, advanced neutron spallation system. Initial case study results are presented, indicating benefits of introducing certain diagram types and their tailoring to domain-typical concerns. A discussion and evaluation of the case study results and the applied research methodology conclude the paper.
