CARIBU Beam Yields for Representative Species

Updated July, 2009

Typical CARIBU intensities for low-energy (stopped) and accelerated beams for the three ²⁵²Cf sources that will be used sequentially.

A more complete list ( for the 1 Ci source) can be found in the CARIBU proposal.

Expected ²⁵²Cf fission source strength:

2.5 mCi ― summer 2009; 80 mCi ― fall 2009; 1 Ci ― early 2010;
