How the Stimulus Is Changing America 2010-08-26T08:45:00Z Yet, at least publicly, those running the synchrotron are thinking not about how to save the young facility but how to grow it. Australian Government Silent on Synchrotron Budget While Scientists Plan Expansion 2011-05-11T19:58:26Z Other large science facilities are also evaluated in 5-year increments, he notes, "so it wouldn't be unusual for a review of synchrotron operations to happen at the last minute."
