A prototype SRFQ resonator optimized for a velocity of {beta}=0.03 and a charge to mass ratio (q/M) of 1/6 has been designed, fabricated and tested. This is a short RFQ structure (only 2{beta}{lambda} long) operating at 57.4MHz. The resonator is made of copper, and a 1.5{mu}m thick layer of electroplated Pb-2at.%Sn is used as the superconductor. The electrical characteristics of the resonator derived from detailed 3-D numerical simulations using the MAFIA codes, and also from measurements on the actual resonator are described. The multipactoring levels could be processed away with ease. Quality factor (Q) > 1 {times} 10{sup 8} is obtained for E{sub a} up to 1 MV/m. Other parameters relevant to superconducting operation are also presented.
