Primary purpose of this experiment is the development of techniques to simplify and make cheaper the construction of the cryomodules. In the current ILC TDR design the helium vessel and the connected pipes are made of expensive titanium. JINR in association with INFN several designs for these transitions have been produced and studied during the last years. The results of measuring microhardness by Vickers microindentation are issued of ~3.8 GPa and the breaking strength was 375 MPa. Helium leak measurements revealed no leaks at a background leak rate of 0.4*10^-10 atm*cc/s. For imitation of use transition sample in real working position, connected with Nb cavity, Nb rings were joint with Nb pipe of samples by EBW. Superposition of all residual stresses may result plastic deformation, failure of welds, and consequently occurrence of a leak. Test result of thermocycles in LHe and in the LN ussued absence of leak at background leak rate ~0.5*10^-10 atm*cc/sec. The results showed the full eligibility of suggested design Nb+Ti+SS transition sample not for only Linear Collider, but for any cryogenic systems.

Wire-based beam instrumentation remains a reference for calibration of many other instruments, providing direct and accurate measurements with high resolution. However beam power increasing of existing and forthcoming ion linacs results in strict constraints on operation modes acceptable for control and diagnostics. Relevant simulations of wire thermal loads are necessary not only for a mode choice, but also for a preliminary design of such instrumentation. Simulations for different wire materials and various beam parameters are made. Features of the model are discussed. Numerical estimations and conclusions are presented in comparison with some experimental results.
