SRFQ2 is the second RFQ superconducting (SC) structure of PIAVE, the positive ion injector of the SC LINAC for heavy ions ALPI, in operation at Legnaro.
During 2001, SRFQ2 was extensively tested at cryogenic temperature reaching its design performance, i.e., 280 kV inter-electrode voltage (equivalent to 25 MV/m peak surface electrical field) at 7 W dissipated power.
This paper describes the treatments, the main difficulties arisen during the tests, the way they were overcome and the measurement sequences that allowed the characterization of SRFQ2 behavior. A brief description of future programs is also given.
