Assembling experience of the first two HIE-ISOLDE cryomodules
/ Therasse, Mathieu (CERN) ; Barlow, Graeme (CERN) ; Bizzaglia, Sauro (CERN) ; Capatina, Ofelia (CERN) ; Chrul, Anna (CERN) ; Demarest, Paul (CERN) ; Dequaire, Julien (Intitek, Lyon, France) ; Deschamps, Jean-Baptiste (CERN) ; Gayde, Jean-Christophe (CERN) ; Gourragne, Max (CERN) et al.
The assembly of the first two cryomodules (CM1 and CM2) of the new superconducting linear accelerator HIE-ISOLDE (High Intensity and Energy ISOLDE), located downstream of the REX-ISOLDE normal conducting accelerator, started one year and half ago. After a delicate assembly phase in the cleanroom which lasted nine months, the first cryomodule was transported to the ISOLDE hall on 2 May 2015 and coupled to the existing REX-ISOLDE accelerator, increasing the energy of the radioactive ion beams from 2.8 to 4.3 MeV per nucleon.

HIE-ISOLDE SC Linac progress and commissioning in 2016
/ Venturini Delsolaro, Walter (CERN) ; Bravin, Enrico (CERN) ; Delruelle, Nicolas (CERN) ; Elias, Michal (CERN) ; Fadakis, Eleftherios (CERN) ; Ferreira Somoza, Jose (CERN) ; Formenti, Fabio (CERN) ; Fraser, Matthew (CERN) ; Gayde, Jean-Christophe (CERN) ; Guillotin, Nicolas (CERN) et al.
After the first successful physics run with radioactive ion beams at HIE ISOLDE, in October 2015 [1], the staged deployment of the linac continued in 2016 by adding a second cryomodule and by refurbishing the first one. During the physics run with one cryomodule, the second cryomodule was being assembled. [...]

Development of SRF cavity tuners for CERN
/ Artoos, Kurt (CERN) ; Burt, Graeme (Lancaster U.) ; Calaga, Rama (CERN) ; Capatina, Ofelia (CERN) ; Capelli, Teddy (CERN) ; Carra, Federico (CERN) ; Dassa, Luca (CERN) ; Delayen, Jean (Old Dominion U.) ; Jones, Thomas (Daresbury) ; Kuder, Norbert (CERN) et al.
Superconducting RF cavity developments are currently on-going for new accelerator projects at CERN such as HIE ISOLDE and HL-LHC. Mechanical RF tuning systems are required to compensate cavity frequency shifts of the cavities due to temperature, mechanical, pressure and RF effects on the cavity geometry. [...]

On the understanding of Q-slope of niobium thin films
/ Aull, Sarah (CERN) ; Junginger, Tobias (CERN) ; Knobloch, Jens (Helmholtz-Zentrum, Berlin ; Siegen U.) ; Sublet, Alban (CERN) ; Valente-Feliciano, Anne-Marie (Jefferson Lab) ; Venturini Delsolaro, Walter (CERN) ; Zhang, Pei (CERN)
The Q-slope of niobium coated copper cavities at medium fields is still the limiting factor for the application the Nb/Cu technology in accelerators. This paper presents a dedicated study of a niobium coating with bulk-like characteristics which shows a Q-slope comparable to bulk Nb at 400 MHz and 4 K. [...]

The HIE-ISOLDE project has been approved by CERN in 2009 and gained momentum after 2011. The final energy goal of the upgrade is to boost the radioactive beams of REX-ISOLDE from the present 3 MeV/u up to 10 MeV/u for A/q up to 4.5. [...]
