The reac­cel­er­a­tor ReA is a state-of-the-art su­per-con­duct­ing linac for reac­cel­er­at­ing rare iso­tope beams pro­duced via in­flight frag­men­ta­tion or fis­sion and subse-quent beam stop­ping. ReA was sub­ject of an up­grade that in­creased its final beam en­ergy from 3 MeV/u to 6 MeV/u for ions with charge over mass equal to 1/4. The up­grade in­cluded a new room-tem­per­a­ture re­buncher after the first sec­tion of ac­cel­er­a­tion, a new β = 0.085 QWR cry­omod­ule and two new beam­lines in a new ex-per­i­men­tal vault. Dur­ing com­mis­sion­ing, beams were ac­cel­er­ated with near 100 per­cent trans­port ef­fi­ciency through the linac and de­liv­ered through beam trans­port lines. Mea­sured beam char­ac­ter­is­tics match those calcu-lated. Fol­low­ing com­mis­sion­ing, sta­ble and long liv­ing rare iso­tope beams from a Batch Mode Ion Source (BMIS) were ac­cel­er­ated and de­liv­ered to ex­per­i­ments. This con-tri­b­u­tion will briefly de­scribe the up­grade, and re­sults from beam com­mis­sion­ing and beam de­liv­ery for ex­peri-ments.

  Lo­cated at CERN, ISOLDE is one of the world’s lead-ing re­search fa­cil­i­ties in the field of nu­clear sci­ence. Ra­dioac­tive Ion Beams (RIBs) are pro­duced when 1.4 GeV pro­tons trans­ferred from the Pro­ton Syn­chro­tron Booster (PSB) to the fa­cil­ity im­pinge on one of the two avail­able tar­gets. The RIB of in­ter­est is ex­tracted, mass-sep­a­rated and trans­ported to one of the ex­per­i­men­tal sta­tions, ei­ther di­rectly, or after being ac­cel­er­ated in the REX/HIE-ISOLDE post-ac­cel­er­a­tor. In ad­di­tion to a Pen­ning trap (REX­TRAP) to ac­cu­mu­late and trans­versely cool the beam and a charge breeder (REXE­BIS) to boost the charge state of the ions, the post-ac­cel­er­a­tor in­cludes a linac with both room tem­per­a­ture (REX linac) and su­per­con­duct­ing (HIE-ISOLDE linac) sec­tions fol­lowed by three HEBT lines to de­liver the beam to the dif­fer­ent ex­per­i­men­tal sta­tions. The lat­est up­grades of the fa­cil­ity as well as a com­pre­hen­sive list of the RIBs de­liv­ered to the users of the fa­cil­ity and the op­er­a­tional ex­pe­ri­ence gained dur­ing the last physics cam­paigns will be pre­sented in this con­tri­bu­tion.
