Conclusions: CTA is a project of a largearrayofCherenkovtelescopesforTeVastronomy. CTA is in the PreparatoryPhasefundedby the EuropeanCommission (October 2010- Sep. 2013). CTA willbelocated in twosites (southern and nothernemispheres). CTA iswellsupported at International level and ithasgoodchancestoberealized. CTA constructionwill start in 2013/2014 CTA willbeoperatedasanobservatory on the base of the scientificmerit INAF isfundedby EC for the preparatoryphase INAF has a major role in the CTA and itispresent in the relevantboards INAF isresponsiblefor the CTA_PPProcurement and for the SST structure&mirrors INAF participatestoseveralCTA_PPactivities (Science, Mirrors, TelescopeStructures, MC, Data Hand., Obs. definition) In the frameworkof the program ASTRI fundedby the ItalianMinistryofResearch : INAF planstobuildan end_to_end prototypeof the DualMirror SST INAF willcontributeto the mirrors and structureof the Single Mirror SST prototype INAF willcontributeto the mirrorsfor MST prototype INAF willsupport the CTA activityancillaryto the ASTRI program B.Sacco relazione al MeraTeV , Merate 4-6 ottobre, 2011
