17. Actilab Kick-off meeting SPES Target Group Conclusions ENSAR – ACTILAB: European contract signed but up to now we do not have green light to go on for fellowship application. INFN involved in two sub-tasks:1) Production 2) Characterization INFN contribution to ACTILAB: 1)development of UCx with CNT in collaboration with CERN two complete targets already available at ISOLDE. 2)we have new materials to be characterized and we are interested to collaborate at porosimetry measurements with Orsay. 2011 is a critical year for us about the material development. The Padova Laboratory is closing and we started the developing of a class A laboratory at LNL devoted to UCx development
