The PIAVE superconducting linac is not only made of rfqs; 8 low {beta} superconducting quarter wave resonators, working at 80 MHz, will give an equivalent acceleration voltage of 7.2 MV; a room temperature triple harmonic buncher working at 40 MHz will match the beam to the rfq input and 2 room temperature, 80 MHz rebunchers will match the beam produced by PIAVE into the linac ALPI. The construction and testing of the first superconducting cavity was more than successful: the resonator, at the design power of 7W, reached 6.3 MV/m corresponding to a total acceleration voltage of 1.13 MV at {beta}=0.047. This result allowed us to increase the linac design accelerating field from 3 MV/m to 5 MV/m. The 7 remaining superconducting cavities are presently under construction, and they will be completed within 1998. While the more conventional, room temperature 80 MHz rebunchers are at the design stage, the triple harmonic buncher, made of 2 quarter wave resonators, was constructed, tested and it is ready for installation.
