	The future experimental program of super heavy element synthesis at GSI desires high intense heavy ion beams at or above the coulomb barrier, exceeding the capabilities of the GSI-UNILAC (Universal Linear Accelerator). Additionally, the existing GSI accelerator chain will be used as an injector for FAIR (Facility for Antiproton and Ion Research) primarily providing high power heavy ion beams at a low repetition rate. Due to this limitations a new dedicated superconducting (sc) continuous wave (cw) linac is proposed to keep the Super Heavy Element (SHE) research program at GSI competitive. The construction of the first linac section has been finished in the 3rd quarter of 2016. It serves as a prototype to demonstrate its reliable operability in a realistic accelerator environment. This demonstrator cryomodule comprises the sc 217 MHz crossbar-H-mode (CH) multigap cavity as the key component of the whole project and two sc 9.3 T solenoids. The performance of the cavity has been extensively tested at cryogenic temperatures. In this contribution the measurement results of initial cold tests will be presented.

	The development for superconducting accelerators has been started at TRIUMF in 2000. The main milestones and material implementations are: 2006 - commissioning of Phase-I of the heavy ion superconducting accelerator ISAC-II, 2010 - Phase-II, 2014 - commissioning of Phase-I of the superconducting electron linear accelerator eLinac. We are using the accumulated experience and resources for farther SRF development at TRIUMF and external projects VECC, RISP, FRIB and SLAC. TRIUMF is also running fundamental studies for SRF and educational program for universities. Status of Superconducting ISAC-II and eLinac accelerators and SRF development aspects, results and plans are discussed.
