Posen, S. JACoW Publishing Geneva, Switzerland Over years of research and development, a variety of thermal treatments have been developed for bulk niobium cavities, providing different high performance capabilities for SRF resonators depending on the application. Key considerations include maximum field, quality factor at a desired field, sensitivity to trapped flux, and reproducibility of performance. In this talk, we overview the last decade of development of heat treatments, as well as what is reliability achieved at different laboratories, and open questions.
