Progress with series production of RFD cavities and preparations for cryostating
Accelerator Upgrade Program (AUP) cavity status and preparations at JLab Work is progressing well for the crab cavity portion of the US contribution to the HL-LHC Project. All contracts are in place with the industrial supplier for the manufacturing of the RF-dipole (RFD) crab cavities, where activities have now reached peak production after years of…

RFD Assembly
Two prototypes of RF dipole cavities which provide horizontal crabbing for the HL-LHC were successfully built at CERN. The frequency tuning setup before the final two welds is shown in the figure below. The frequencies of both cavities were within 100 kHz (negligible) showing the surgical precision in the manufacturing techniques for such a complicated…
