SRF-related activities at JLab are varied and increasing. Operation of CEBAF at 5.7 GeV for nuclear physics is now routine. There has been significant progress in the development and testing of components and subsystems for a new cryomodule design for coming upgrades of the JLab CEBAF and FEL. Construction of the first such module has begun, and further optimization studies continue. Jefferson Lab joined the collaboration to build the Spallation Neutron Source (SNS). JLab will contribute 81 cavities in 23 SNS cryomodules. Prototyping of the beta. 0.61 and 0.81 cavities is nearing completion. Development and testing of the high-power coaxial input coupler for SNS is underway. Fresh efforts have been initiated to pursue improved understanding and control of SRF surfaces. JLab has led discussions and development of modern low-level rf controls tailored for power-efficient operation of high-gradient SRF cavities in lightly-beamloaded, cw applications. To support these efforts, major upgrades and renovations to the JLab SRF facilities and information infrastructures are underway. The lab has recognized the importance of SRF to future developments in the accelerator community by the creation of the new Institute for SRF Science and Technology.
