ISBN: 9783659680489 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Fusion Reactor to produce energy without nuclear waste. The total energy release in the (D, T) reaction is 17.6 MeV. A 100% interaction of deuterium and tritium nuclei in the target ensures the energy release W = 17.6 * 106 * 1.5 * 1014 = 3.5*1021 eV or approximately 560 J. Assuming that one gram of TNT releases 4 kJ of energy, the energy of a microburst in this case will be equal to 140 mg of TNT. When the accelerator is operated in the continuous mode, f 0in = 2.4 * 107 tube segments can be accelerated per one second. If each segment releases 560 J of energy during the interaction with the...
