原始语种摘要: Nb3Sn has potential to become the material of choice for fabrication of SRF cavities. The higher critical temperature of Nb3Sn potentially allows for an increased operational temperature in SRF cavities, which could enable a simplification of the cryogenic system, leading to significant cost reduction. We present extended characterization of a Nb3Sn coated Nb cavity prepared at Cornell University. Using a combination of thermometry during cavity RF measurements, and structural and analytical characterization of the cavity cutouts, we discovered Nb3Sn coating flaws in regions that exhibit significant heating during the RF testing. Results of extended comparison of cavity cutouts with different dissipation profiles not only indicate the cause of...
