  First ac­cel­er­a­tion of heavy ion beams with a su­per­con­duct­ing con­tin­u­ous wave HIM/GSI CW-Linac After suc­cess­ful RF-test­ing of a new su­per­con­duct­ing Linac RF-cav­ity at GSI Helmholtzzen­trum für Schw­e­ri­o­nen­forschung and a short com­mis­sion­ing and ramp up time of some days, this 15-gaps Cross­bar H-cav­ity ac­cel­er­ated first time heavy ion beams with full trans­mis­sion up to the de­sign beam en­ergy. The de­sign ac­cel­er­a­tion gain of 3.5 MV in­side a length of less than 70 cm has been ver­i­fied with heavy ion beam of up to 1.5 par­ti­cle mkA. The mea­sured beam pa­ra­me­ters show a nice beam qual­ity. The ma­chine com­mis­sion­ing with beam is a mile­stone of the R&D work of Helmholtz In­sti­tute Mainz and GSI in col­lab­o­ra­tion with Goethe Uni­ver­sity Frank­furt in de­vel­op­ment of the su­per­con­duct­ing heavy ion con­tin­u­ous wave lin­ear ac­cel­er­a­tor CW-Linac.

  The new post-strip­per DTL at GSI shall ac­cel­er­ate ura­nium beams with space charge in­duced tune de­pres­sions of up to 37% to 11.4 MeV/u. Emit­tance di­lu­tion must be kept below few per­cent. How­ever, the lay­out must also allow for de­liv­ery of light­est ions to just 3.0 MeV/u. This broad-banded range of re­quire­ments im­poses huge chal­lenges on the lay­out and fab­ri­ca­tion es­pe­cially of the cav­i­ties and drift tube mag­nets.

For fu­ture ex­per­i­ments with heavy ions near the coulomb bar­rier within the su­per-heavy el­e­ment (SHE) re­search pro­ject a multi-stage R&D pro­gram of GSI/HIM and IAP is cur­rently in progress. It aims for de­vel­op­ing a su­per­con-duct­ing (sc) con­tin­u­ous wave (CW) LINAC with mul­ti­ple CH cav­i­ties as key com­po­nents down­stream the High Charge State In­jec­tor (HLI) at GSI. The LINAC de­sign is chal­leng­ing due to the re­quire­ment of in­tense beams in CW mode up to a mass-to-charge ratio of 6, while cov­er­ing a broad out­put en­ergy range from 3.5 to 7.3 MeV/u with un­changed min­i­mum en­ergy spread. Test­ing of the first CH-cav­ity in 2016 demon­strated a promis­ing max­i­mum ac­cel­er­at­ing gra­di­ent of Ea = 9.6 MV/m; the world­wide first beam test with this sc multi-gap CH-cav­ity in 2017 was a mile­stone in the R&D work of GSI/HIM and IAP. In the light of ex­pe­ri­ence gained in this re­search so far, the beam dy­nam­ics lay­out for the en­tire LINAC has re­cently been up­dated and op­ti­mized.
