N2 - The 704 MHz high current superconducting cavity has been designed with considerationof both performance of fundamental mode and damping of higher order modes. A copperprototype cavity was fabricated by AES and delivered to BNL. RF measurements were carriedout on this prototype cavity, including fundamental pass-band and HOM spectrummeasurements, HOM studies using bead-pull setup, prototyping of antenna-type HOM couplers.The measurements show that the cavity has very good damping for the higher-order modes,which was one of the main goals for the high current cavity design. 3D cavity models weresimulated with Omega3P code developed by SLAC to compare with the measurements. The paperdescribes the cavity design, RF measurement setups and results for the copper prototype.The progress with the niobium cavity fabrication will also be described.
