SPES (Se­lec­tive Pro­duc­tion of Ex­ot­ic Species) is an INFN pro­ject to de­vel­op a Ra­dioac­tive Ion Beam (RIB) fa­cil­i­ty as an in­ter­me­di­ate step to­ward EU­RISOL. The SPES pro­ject is part of the INFN Road Map for the Nu­cle­ar Physics de­vel­op­ment in Italy and is sup­port­ed by LNL and LNS the INFN Na­tion­al Lab­o­ra­to­ries of Nu­cle­ar Physics in Leg­naro and Cata­nia. The Lab­o­ra­tori Nazion­ali di Leg­naro (LNL) was cho­sen as the fa­cil­i­ty site due to the pres­ence of the PI­AVE-ALPI ac­cel­er­a­tor com­plex, which will be used as re-ac­cel­er­a­tor for the RIBs. The SPES pro­ject is based on the ISOL method with an UCx Di­rect Tar­get and makes use of a pro­ton driv­er of at least 40 MeV en­er­gy and 200 mi­croA cur­rent. Neu­tron-rich ra­dioac­tive beams will be pro­duced by Ura­ni­um fis­sion at an ex­pect­ed fis­sion rate in the tar­get in the order of 10¹³ fis­sions per sec­ond. The key fea­ture of SPES is to pro­vide high in­ten­si­ty and high­qual­i­ty beams of neu­tron rich nu­clei to per­form fore­front re­search in nu­cle­ar struc­ture, re­ac­tion dy­nam­ics and in­ter­dis­ci­plinary fields like med­i­cal, bi­o­log­i­cal and ma­te­ri­al sci­ences. The ex­ot­ic iso­topes will be re-ac­cel­er­at­ed by the ALPI su­per­con­duct­ing linac at en­er­gies up to 10AMeV for mass­es in the re­gion of A=130 amu with an ex­pect­ed rate on tar­get of 10⁹ pps.
