SPES is a fa­cil­i­ty to be built at Na­tion­al In­sti­tute of Nu­cle­ar Physics (INFN lab­o­ra­to­ry, Leg­naro, Italy) in­tend­ed to pro­vide in­tense neu­tron-rich Ra­dioac­tive Ion Beams (RIBs) di­rect­ly hit­ting a UCx tar­get with a pro­ton beam of 40 MeV and 0.2 mA; RIBs will be pro­duced ac­cord­ing to the ISOL tech­nique and the new idea that char­ac­ter­ize the SPES pro­ject is the de­sign of the pro­duc­tion tar­get: we pro­pose a tar­get con­fig­u­ra­tion ca­pa­ble to keep high the num­ber of fis­sions, low the power de­po­si­tion and fast the re­lease of the pro­duced iso­topes. In this work we will pre­sent the re­cent re­sults on the R&D ac­tiv­i­ties re­gard­ing the mul­ti-foil di­rect UCx tar­get.

The re­cent de­vel­op­ment in laser ac­cel­er­a­tion of pro­tons and ions has stim­u­lat­ed ideas for using this con­cept as in­no­va­tive and com­pact ther­a­py ac­cel­er­a­tor. While cur­rent­ly achieved pa­ram­e­ters do not allow a re­al­is­tic con­cep­tu­al study yet we find that our sim­u­la­tion stud­ies on ion col­li­ma­tion and trans­port, based on out­put data from the PHE­LIX ex­per­i­ment, al­ready give a use­ful guid­ance. Of par­tic­u­lar im­por­tance are the chro­mat­ic and ge­o­met­ric aber­ra­tions of the first col­li­ma­tor as in­ter­face be­tween the pro­duc­tion tar­get and a con­ven­tion­al ac­cel­er­a­tor struc­ture. We show that the re­sult­ing 6D phase space match­es well with the re­quire­ments for syn­chrotron in­jec­tion.

Laser cool­ing for bunched Mg ion beam with the ki­net­ic en­er­gy of 40 keV has been ap­plied with S-LSR at ICR, Kyoto Uni­ver­si­ty. Up to now, clear peak­ing of equi­lib­ri­um mo­men­tum spread after laser cool­ing has been ob­served at such a syn­chrotron tune as res­onates with the hor­i­zon­tal be­ta­tron tune, which is con­sid­ered to be due to heat trans­fer from the hor­i­zon­tal de­gree of free­dom to the lon­gi­tu­di­nal one. In order to demon­strate trans­verse cool­ing by ob­ser­va­tion of re­duc­tion of the hor­i­zon­tal beam size, spon­ta­neous emis­sion from laser in­duced ex­cit­ed state of the Mg ion, has been ob­served with the use of CCD cam­era. Some re­duc­tion of hor­i­zon­tal beam size has been ob­served with a cer­tain syn­chrotron tune, a lit­tle bit small­er com­pared with the frac­tion­al part of the hor­i­zon­tal tune.
