I don't know if other Vorts thought of this already... but I had a minor epiphany regarding the radiation that MFMP measured in GS5.2. We identified this radiation tentatively as bremsstrahlung. This has certain implications. Bremsstrahlung requires that the high speed electrons impact on a high atomic mass element so as to be accelerated/decelerated quickly to produce the radiation. It could be that the stainless steel can that contained the fuel was an important component in seeing the bremsstrahlung. Without the can, there would still be the Ni for the electrons to hit, but the Ni is covered with light atomic mass Li. If the electrons were to strike alumina (no fuel can present), I don't think there would be nearly as much bremsstrahlung because alumina is comprised of light elements.
Thus, the stainless steel can for the fuel may be an important component for seeing the bremsstrahlung. Bob Higgins
