The development of high power, unconditionally stable solid-state amplifiers for superconducting low-beta cavities, performed at Laboratori Nazionali di Legnaro in the framework of the EURISOL Design Study, has led to the construction and testing of two, newly designed 10 kW units that can be used both individually or coupled together to obtain a 20 kW source. Characteristic of this family of amplifiers, based on parallel assemblies of 300W modules equipped with mosfets and individual circulators, is their possibility of operating in any matching conditions and also, at a reduced power, in case of failure of one mosfet. Characteristics of the amplifiers and of the high power combiner will be described, and their performance and test results will be reported.

The low-b section of the PIAVE-ALPI superconducting linac is being upgraded in order to increase its energy gain from approximately 10 to about 20 MeV/q. This large increase of the accelerating voltage will be obtained by increasing by 20% the number of low-beta bulk niobium quarter-wave resonators and by upgrading the old rf system, underdimensioned in comparison with the resonator performance. This will lead to a significant enhancement of the linac capabilities, including the possibility of acceleration well above the Coulomb barrier heavy ions with any mass number. Status and technical details of the upgrade program will be described.
