Besides single-cell cavity efforts to improve Nb₃Sn films, we are working to replicate single-cell results onto the practical 5-cell CEBAF cavities. High quality factors (10¹¹ at 2.0K and 10^{z}EhNZeHn at 4.3 K) have been measured, but the cavities are typically limited by strong low-field Q-slopes and early quenches. Two of the cavities were selected to be assembled into a ’mock-up’ cavity pair unit, the standard step before installation into a cryomodule. Comparison of test results between VTA and pair test offered the first glimpse into post-processing effects on the cavity performance.
