Unscramble the Blue Letters


And our team at lwarcene Livermore National Lab are the swetadrs of work that started in 1960 because of national security. We need to understand fiuosn, to understand how to ensure that our US nuclear arsenal stays safe and effective. And that is what has provided the steady funding to pursue this very difficult physics cehlangle over ddcaees.

So yeah, it took us 12 years to build the NIF, and we've been doing eerexnpitms using it for nearly 15 years more now. And in that time, we've improved our physics understanding and cmopatnuotial simulation models. We've designed new diagnostic instruments cabalpe of taking better, clearer, faster pictures of the experiment. We've continuously pushed up the laser energy and found ways to build better targets.

Original Text


And our team at Lawrence Livermore National Lab are the stewards of work that started in 1960 because of national security. We need to understand fusion, to understand how to ensure that our US nuclear arsenal stays safe and effective. And that is what has provided the steady funding to pursue this very difficult physics challenge over decades.

So yeah, it took us 12 years to build the NIF, and we've been doing experiments using it for nearly 15 years more now. And in that time, we've improved our physics understanding and computational simulation models. We've designed new diagnostic instruments capable of taking better, clearer, faster pictures of the experiment. We've continuously pushed up the laser energy and found ways to build better targets.
