	Superconducting (SC) solenoids provide efficient focusing of ion beams in SC linacs. This talk will discuss design, installation and operational experience of long cryomodules containing multiple SC solenoids. The techniques for the alignment of cavity-solenoid string will be presented. The solenoid assemblies include X-, Y-steering coils and does not require any iron shielding. The studies of SRF cavity properties after the quenching next to the solenoid will be presented.

This will include cavity performance measurements where we found residual resistances of < 3 nanoOhms at low fields and peak voltage gains of 5.9 MV, which corresponds to peak surface fields of 134 MV/m and 144 mT electric and magnetic respectively.
