The pos­i­tive ion in­jec­tor for the PI­AVE-ALPI com­plex con­sists of an ECR ion source placed on a high volt­age plat­form. A 14.4 GHz ECRIS named Alice, de­signed and con­struct­ed at LNL in the early &##8216;90, re­li­ably de­liv­ered gaseous beams to the Su­per­con­duct­ing RFQ PIAVE for nu­cle­ar physics ex­per­i­ments until 2008. The re­quests for heavy ion beams of in­creased cur­rent and en­er­gy, need­ed to per­form the ex­per­i­ments planned for the next years with the AGATA demon­stra­tor, prompt­ed us to up­grade our in­jec­tor with a new ECR source ca­pa­ble of high­er out­put beam cur­rents and high­er charge states. This ac­tiv­i­ty start­ed in 2008 and was com­plet­ed at the be­gin­ning of 2009. A 14.5 GHz, SU­PER­NANOGAN type ECRIS built by Pan­tech­nik, was in­stalled in our re­fur­bished high volt­age plat­form in July 2008. The space avail­able for main­te­nance in the plat­form was in­creased and a new lead shield­ing for X-rays has been set up. The water cool­ing cir­cuits have been re­designed to de­liv­er dif­fer­ent flux­es and inlet pres­sures to the equip­ment mount­ed on the plat­form (plas­ma cham­ber, ex­trac­tion elec­trodes, bend­ing dipole and power sup­ply). A new safe­ty sys­tem has been im­ple­ment­ed in order to cope with new and more de­mand­ing safe­ty rules. A lot of at­ten­tion has been paid to the op­ti­mi­sa­tion of the in­jec­tion line with new di­ag­nos­tic de­vices for beam char­ac­ter­i­sa­tion (mov­able slits, emit­tance mea­sure­ment tools). Com­mis­sion­ing of the new source and in­jec­tor with beams has start­ed and first re­sults will be re­port­ed.
