The new positive ion injector PIAVE at LNL

The construction of a positive ion injector for the linac ALPI, named PIAVE, at Laboratori Nazionali di Legnaro was funded in 1996. The beam parameters of the injector, consisting of two superconducting radiofrequency quadrupoles (SRFQ) and eight superconducting quarter wave resonators (QWR) for an equivalent voltage of about 8 MV (U/sup 28+/ beam), are fixed. The building is ready, infrastructures and beam transport lines are being ordered. The superconducting RFQs are in the prototyping phase. The general status of the project is reported in this paper, including cryostat and cryogenics, bunching systems, diagnostic devices and electronic control systems.
