Disclosed is a method for injecting electrons of predetermined energy and quantity into an inertial confinement fusion fuel-derived plasma to enhance the pre-ignition conditions of thermonuclear fusion reactions using a plurality of electron or x-ray sources to control the ratio of ion and electron temperatures of the plasma. The method comprises providing a central target chamber for receiving a spherical pellet of fusion fuel; and providing a plurality of energy drivers arranged in symmetrical pairs about the fusion fuel pellet, and oriented to direct a first energy pulse of optical laser light, X-ray pulses or ions into the fusion fuel in a 3-dimensionally symmetric manner about the fusion fuel pellet and providing a plurality of electron sources, each of which creates an electron beam of a predetermined energy and quantity. The plurality of energy drivers are operated for illuminating and ionizing the spherical pellet to create a fusion fuel-derived plasma; and then the plurality of energy drivers are operated to cause the electron beams to permeate the fusion fuel-derived plasma. The energy level of the electron beams are adjusted via a controlled input. The current of the electron beams are adjusted via a controlled input. The electron sources focus the electron beams into the fusion fuel-derived plasma. The plurality of electron sources are controlled so that they inject a pulse of electrons of predetermined energy, pulse width, and quantity into the fusion fuel-derived plasma as a predetermined interval of picosecond or finer increments after said first energy pulse. An RF pulse is injected with a predetermined delay from the first energy pulse, into the fusion fuel-derived plasma. |
