Summary
The Operation Request Gatekeeper (ORG) software securely manages remote tokamak diagnostic control requests. It ensures safety and efficiency by validating and authenticating all modifications before execution.
Area of Science:
- Nuclear Fusion Engineering
- Plasma Physics
- Control Systems Software
Background:
- Tokamak diagnostic settings require frequent modifications for experimental needs.
- Remote control of diagnostics faces security and efficiency challenges.
Purpose of the Study:
- To develop and test a software system for secure remote modification requests of tokamak diagnostic settings.
- To address security and efficiency challenges in remote diagnostic control.
Main Methods:
- Designed and implemented the Operation Request Gatekeeper (ORG) software system.
- Integrated ORG with ITER CODAC and tested with KSTAR Plasma Control System.
- Performed user authentication, authorization, grammar validation, and validity checks.
Main Results:
- A prototype ORG was successfully developed and met initial requirements.
- Demonstrated secure and efficient remote request submission.
- Validated ORG's functionality with real-world tokamak systems.
Conclusions:
- The Operation Request Gatekeeper (ORG) effectively enables secure and efficient remote control of tokamak diagnostics.
- ORG provides a robust framework for managing modification requests in fusion research.
- The system shows promise for future tokamak operations and remote experimentation.
