Abstract
In the framework of the ALPI upgrading, a new positive ion injector is foreseen in order to be able to accelerate ions with masses of the or der of 200 and with high charge states from the velocity of beta = 0.0 09 up to beta = 0.055. The structures chosen for that velocity range a re superconducting radio frequency quadrupoles operating at a frequenc y of 80 MHz, which is the operating frequency of the ALPI low beta cav ities. The paper describes the current status of the project including beam dynamics, cavity design, beam transfer lines and vacuum, control and cryogenic systems.
