JUROGAM + RITU + GREAT

RDT 43 ESS Total efficiency 4.2% at 1.3 MeV

JUROGAM 2 Beyond Summer 2007?

We have to decide now!

Gammapool meets 23/9/5 SAGE with Phase 1 detectors 38 ESS Total efficiency 3.7% at 1.3 MeV

JUROGAM 2 SAGE with Phase 1 and Clover detectors 10 phase 1 and 22 Clover Total efficiency 5.1% at 1.3 MeV Phase 1 (10) Clover (22) 1% 4.1% LNL bid for CLARA June 2007 for 2 years!

What about AGATA? Demonstrator
