  30. The Conclusions • In 2013 common GSI-JINR project started with resources (@around 3 M USD) released to develop corresponding infrastructure for massive production of modules and, especially, supermodules at LHEP JINR by mid-2015 for the BM@N and CBM STS projects, firstly, and NICA-MPD ITS, afterwards Through years 2008-2013 the CBM-MPD STS Consortium demonstrated self-sustained growth of R& D activity which could be successfully accomplished within 1,5 -2 years • Young generation recruitment and training is the basic problem of the project to be discussed tomorrow in more details as well as more involvement of physicists from the Universities of both capitals of Russia Thank you for your attention!
