I'm wondering if you first came with the cool name PUMA and tried to unfold it, or it was the other way around...
I guess you tried to build a TIGER: Tritium Induced Gamma E... Enhanced Radiation. Hey, could we build "Tritium Induced Gamma Enhanced Radiation". Makes no sense? Back to the drawing board.
I think so ;)
You should ask the PI of the PUMA experiment. But I guess the name came after :D
