First Article ESR 591 Single Cell Cavity

The EIC Project is a new particle accelerator being installed at Brookhaven National Laboratory. Thomas Jefferson National Accelerator Facility (TJNAF) is providing twenty-four (24) new 591 MHz single-cell cavities to the EIC Project. Seventeen (17) of these cavities will be used in the new EIC Electron Storage Ring (ESR), five (5) will be used in the new EIC Hadron Storage Ring (HSR), one (1) will be used to assemble a spare cryomodule cold-mass, and one (1) is a Risk mitigation spare. In both the ESR and HSR these cavities will operate at 591 MHz, 4.0 MV, and 2.0 K, while coupling up to 800 kW of power to multi-ampere beams.
