Abstract
A novel bidirectional, remotely operable diagnostic calorimeter has been developed for the Comprehensive Research Facility for Fusion Technology (CRAFT) Negative Neutral Beam Injection (NNBI) test platform to evaluate beam uniformity and divergence. The system employs 1D-carbon fiber composite (CFC) tiles, selected for their exceptional thermal conductivity and high-temperature resistance, ensuring accurate diagnostics under extreme operating conditions. The calorimeter comprises a 4 × 4 array of CFC tiles, a robust support structure, and a precise linear motion system, enabling accurate positioning within the vacuum chamber. Integrated infrared (IR) cameras provide thermal imaging capabilities, while finite element analysis (FEA) confirms the thermodynamic performance of the CFC tile and the mechanical reliability of the design. Following successful fabrication and installation, the system was fully integrated into the NNBI test platform in early 2024. This diagnostic calorimeter offers a reliable solution for evaluating the characteristics of negative neutral beams and establishes a solid foundation for future experimental research in fusion technology.
