Description
The High Intensity heavy-ion Accelerator Facility (HIAF), currently under construction, will employ a series of superconducting RF (SRF) cavities in its injector linac (iLinac) to accelerate heavy-ion beams. Comprehensive performance validation of each SRF cavity in a horizontal test stand prior to its installation in the accelerator tunnel is a critical prerequisite for the successful commissioning of the iLinac. To this end, we have developed an advanced Low-Level RF (LLRF) automation and diagnostic system for the horizontal test stand of HIAF's low-beta SRF cavities. This system integrates several key functions: high-precision measurement of cavity parameters, automated conditioning at both room and cryogenic temperatures, reliable quench detection, and stable closed-loop operation. The successful application of these advanced strategies not only validates that the cavity performance meets design specifications but also significantly enhances the efficiency and consistency of the testing process, laying a solid foundation for the subsequent installation and commissioning of the HIAF iLinac.
