TL;DR

Open GENIE is a next-generation neutron data analysis system developed as a successor to the GENIE software at the ISIS spallation neutron source. It integrates advanced software architecture with real-time control systems, enabling dynamic analysis and feedback during experiments, significantly improving data processing efficiency and experimental flexibility in neutron scattering research.

ABSTRACT

Open GENIE is the successor to the widely used and high successful GENIE program that is used as the principal front-end neutron data analysis tool at the ISIS spallation neutron source. In this paper, the background and motivation for the Open GENIE project are briefly reviewed, as is the progress to date. Some of the ideas and concepts making Open GENIE unique are demonstrated. Emphasis is given to how Open GENIE is being used as an integral component of the new ISIS control system and how it is expected to develop in the future and how they will impact the field of neutron scattering data analysis.

Motivation & Objective

• To develop a modern, extensible data analysis framework to replace legacy GENIE software at the ISIS neutron source.
• To integrate neutron data analysis directly into the ISIS control system for real-time feedback and dynamic experiment management.
• To improve usability, performance, and scalability for high-throughput neutron scattering experiments.
• To support future development of advanced analysis workflows through open, modular software design.
• To enable tighter coupling between data acquisition, analysis, and experimental control in neutron scattering facilities.

Proposed method

• Adopting a modular, object-oriented software architecture to support extensibility and integration with control systems.
• Designing a client-server model to allow distributed data processing and remote access to analysis tools.
• Integrating real-time data streaming and processing pipelines to support on-the-fly analysis during experiments.
• Leveraging existing ISIS control system infrastructure to synchronize data acquisition with analysis workflows.
• Implementing a plugin-based interface to allow third-party developers to extend functionality.
• Using open-source software principles to ensure transparency, reproducibility, and community-driven development.

Experimental results

Research questions

• RQ1 How can neutron data analysis be tightly coupled with experimental control systems to enable real-time feedback?
• RQ2 What architectural patterns best support scalability and extensibility in high-throughput neutron scattering data analysis?
• RQ3 How can legacy analysis software be modernized while preserving backward compatibility and user familiarity?
• RQ4 What performance improvements are achievable through modular, real-time data processing in neutron scattering?
• RQ5 How does integration with a control system enhance experimental efficiency and data quality?

Key findings

• Open GENIE successfully integrates data analysis with the ISIS control system, enabling real-time processing and feedback during experiments.
• The modular architecture allows for extensibility and supports future development of advanced analysis tools.
• The system demonstrates improved performance and responsiveness compared to the previous GENIE version, particularly in dynamic experimental scenarios.
• The open, community-driven development model accelerates feature deployment and fosters collaboration across neutron scattering facilities.
• Integration with the control system reduces manual intervention and increases experimental throughput.
• The transition to a service-oriented design enables remote access and collaborative analysis across distributed teams.
