Paragraph:
Scientists are working hard to develop nuclear fusion reactor. Nuclei of heavy hydrogen, 21H known as deuteron and denoted by D can be thought of as a candidate for fusion reactor. The D - D reaction is 21H+21H→32He+n+ energy. In the core of fusion reactor. A gas of heavy hydrogen is fully ionized into deuteron nuclei and electrons. This collection of 41H nuclei and electrons is known as plasma. The nuclei move randomly in the reactor core and occasionally come close enough for nuclear fusion to take place. Usually, the temperatures in the reactor core are too high and no material wall can be used to confine the plasma. Special techniques are used which confine the plasma for a time t0 before the particles fly away from the core. If n is the density (number/volume) of deutrons, the product t 0 is called Lawson number. In one of the criteria, a reactor is termed successful if Lawson number is greater than 5×1014scm−3.
It may be helpful to use the following : Boltzmann constant k=8.6×10−5eV/K; e24πε0=1.44×10−9eVmQuestion:
In the core of nuclear fusion reactor, the gas becomes plasma because of
