Community Endorsements for GRETA


“The SAC viewed the science addressed in your submission as having the highest scientific priority and this was communicated to the FRIB Laboratory Director. […] The SAC reiterates the support for GRETA in the LRP and looks forward to the initiation of GRETA construction following the successful campaign of GRETINA at the NSCL..” 
-- 2011 FRIB SAC Report  


 “Construction of GRETA should begin immediately upon the successful completion of the GRETINA array” 
-- 2007 NSAC Long Range Plan 


“The detection of γ-ray emissions from excited nuclei plays a vital and ubiquitous role in nuclear science. The physics justification for a 4π tracking array is extremely compelling, spanning a wide range of fundamental questions in nuclear structure, nuclear astrophysics, and weak interactions.” 
-- 2002 NSAC Long Range Plan
