1. Fusion Theory/Deuterium Sue

2. IEC Fusion ProcessTwo concentric spherical grids are located in a chamber. One grid is smaller than the other one by a ratio about 1:5.This chambers air would be evacuated and backfilledwith deuterium gas.The smaller grids charge is negative while the outergrids charge is positive. How?After deuterium gas entered, they become ionized dueto high voltage placed across inner and outer grids.This process is called field emission. Where arethose electrons? And why do they become ionizeddue to high voltage? 3. Those ionized positive deuterium atoms, called deuteron,accelerate towards the center of the inner grid, which ischarged negatively.Most of the ions do not collide head on. Only some do. Those missed ions will oscillate back and forth the central region until they become fused. (Ions did not collide would decelerate out the other side, stop, and accelerate back to the center.)By using dual grid, we trap those positive ions and increaseprobability of fusion rise. (Negative inner grid attracts theions while positive outer grid traps those ions sincepositive grid and positive ions repel each other.) 4. What happens when they fuse? D-D FusionBy colliding two deuterons(proton+neutron), fusion reactions occurs, called D-D FusionD+D = He3 (.82mev) + n (2.45mev) Helium 3 atom, (stable), with a kinetic energyof .82mev and a Neutron of 2.45 mev kineticenergy.D+D= T + p + 4.03mev a tritium atom, (radioactive), with a kineticenergy of 1 mev and a proton of 3 mev kineticenergy. 5. What is deuterium?also called heavy hydrogen, isotope ofhydrogen with atomic weight of approximately2. Its nucleus, consisting of one proton andone neutron, has double the mass of thenucleus of ordinary hydrogen. Deuterium is astable atomic species found in naturalhydrogen compounds to the extent of 0.014 to0.015 percent. *Hydrogen initially have onlyone proton with atomic number 1. 6. Why use deuterium as a fuel for fusion?Because it is abundant on Earth and works for fusion. Other fuels such as tritium is harder to obtain. The deuterium part of the fuel does not pose a great problembecause about 1 part in 5000 of the hydrogen in seawater is deuterium.This amounts to over 1015 tons of deuterium. Viewed as a potential fuelfor a fusion reactor, a gallon of seawater could produce as much energyas 300 gallons of gasoline. The tritium part of the fuel is more problematic- there is no sizable natural source since tritium is radioactive with a half-life of about 10 years. It would have to be obtained by breeding the tritiumfrom lithium.
