NIF allocates a small fraction (~8%) of the facility’s time to “Discovery Science”. 8 teams completed the initial allocation in FY15.

Duffy (Princeton), Jeanloz (UCB) Wark (Oxford) Jeanloz (UCB), Hemley (CIW) Falcone (UCB), Neumayer (GSI)

Casner (CEA) Kane (LLNL), Pound (Maryland) Kuranz, Drake (Mich) Sakawa (Osaka), Takabe (HZDR)

Discovery Science had 44 target shots in FY15 versus 26 DS shots total in FY10-FY14
