In the current ILC TDR design both the helium vessel shell and the connected pipes are made of expensive titanium, one of the few metals that can be welded to niobium by the electron beam technique. We describe the construction and performance of transition elements, obtained by explosion welding, that can couple the niobium cavity with a stainless steel helium vessel. Several designs for these transitions have been produced and studied showing varying levels of reliability. Based on this experience a new design, including a minimal titanium intermediate layer, has been built. Preliminary tests yield impressive results, indicating a very strong resistance of the bon PB - JACoW CP - Geneva, Switzerland SP - 913 EP - 916 KW - cryomodule KW - niobium KW - cryogenics KW - neutron KW - cavity DA - 2015/06 PY - 2015 SN - 978-3-95450-168-7 DO - 10.18429/JACoW-IPAC2015-MOPHA052 UR - http://jacow.org/ipac2015/papers/mopha052.pdf ER -
