Progress and Challenges in Traveling-Wave SRF cavity development at Fermilab

Year: 2024

Type: conference-paper

Abstract: Demonstration of a Traveling-Wavw resonance excitation in the 3-cell structure in 2K liquid helium• The early stages of TW SRF cavity development have been funded by several SBIR grants to Euclid Techlabs (DOE SBIR Grant # DE-SC0006300) which were completed in collaboration with Fermilab.• A 1.3GHz 3-cell proof-of-principle TW SRF Nb cavity was fabricated.The cavity was processed by bulk BCP, degas, and final light BCP.After final BCP, the cavity cells had a field profile tuning in SW mode to the simulated field distributions from CST for 3 cell TW mode.• Special 2D WG tuner to control TW resonance in the 3-cell was also fabricated.The preliminary tuner mechanical test at room and liquid nitrogen temperatures were successful.A cold test with the 3-cell being prepared. Development of a half-meter scale (7-cell) TW cavityAug.
