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 pro­duc­tion tar­get of the SPES pro­ject is going to pro­duce neu­tron rich iso­topes (Z > 40) by di­rect­ly im­ping­ing a 40 MeV pro­ton beam of I = 200 μA on 7 coax­i­al UCx porous thin disks. In order to pro­duce a very in­tense ex­ot­ic beam, a strong ef­fort on tar­get ion source de­vel­op­ment is nec­es­sary. In the SPES fa­cil­i­ty the stan­dard ISOL­DE MK1 sur­face ion source is used for 1+ ions pro­duc­tion; in this kind of source a high tem­per­a­ture cav­i­ty of Tung­sten (also Tan­ta­lum or Rhe­ni­um) is able to ion­ize ef­fi­cient­ly the al­ka­lis, rare-earth el­e­ments and low ion­iza­tion po­ten­tial molecules. In this way the ions are ready to be ex­tract­ed and ac­cel­er­at­ed by means of an ex­trac­tion elec­trode kept at 60 kV. In this work the Struc­tural-Ther­mal-Elec­tric be­haviour of the MK1 ion source is stud­ied, con­sid­er­ing a full 3-D Cou­pled Struc­tural-Ther­mal-Elec­tric ANSYS® Fi­nite El­e­ment model; FE re­sults are com­pared with both po­ten­tial dif­fer­ence and tem­per­a­ture mea­sure­ments. To study the Elec­tro­stat­ic field of the ex­trac­tion zone close to the ion source an ANSYS® FE Elec­tro­stat­ic model was de­vel­oped.
