Ignition Component fuel moisture (FFM) which expresses the effective moisture content of the fine fuels. The closer the initial temperature of the fuel is to the ignition temperature, the more likely a fire will result when a firebrand in introduced into the fine fuel complex, since not a much energy is required to raise the fuel particle to its ignition temperature. Ignition Component The Ignition Component is a number which relates the probability that a fire will result if a firebrand is introduced into a fine fuel complex. The ignition component can range from 0 when conditions are cool and damp, to
Fusion ignition of deuterium and tritium, which are both isotopes of hydrogen, in order to compress the isotopes to a fraction of their original size, and fuse them into helium atoms (releasing neutrons in the process). In January 2012, National Ignition Facility Director Mike Dunne predicted in a Photonics West 2012 plenary talk that ignition would be achieved at NIF by October 2012. However, , NIF is operating at conditions about 1/10 to 1/3 of breakeven. Confusingly, by LLNL definitions, ignition and breakeven occur at the same point, due to specifics of their experiment. Experts believe that achieving fusion ignition is the
