TI - A Novel Approach to Producing High Gradient and Q₀ Cavities in Non-Ideal Furnaces J2 - Proc. of SRF2021, East Lansing, MI, USA, 28 June-02 July 2021 CY - East Lansing, MI, USA T2 - International Conference on RF Superconductivity T3 - 20 LA - english AB - Since the discovery of nitrogen doping in 2014, infusion in 2017, "mid-T bakes in 2018; the reproducibility in both Q₀ and gradient has been proven to be highly variable between facilities and even within the same furnace within a facility*. Multiple studies have pointed to possible contamination from pumps, non-Molybdenum frame outgassing within a hot zone, gas purity issues, and cross-contamination between furnace runs. The traditional approach to mitigating these effects is using niobium furnace caps, high-temperature furnace burnout runs, and expensive pump replacements. We will show multiple examples of a novel approach to increasing Q₀ and Q₀+E_{acc}, using a simple treatment after a furnace treatment or doping + light EP. We will also outline the possible workflows using this new technique in production. PB - JACoW Publishing CP - Geneva, Switzerland ER -
