Scientists have learned how to get energy from the laser fusion. In this process, there is only one problem - get the output more energy than was spent on fuel ignition. Installation on National Ignition Facility (NIF) conducted an experiment that the output after ignition demonstrated energy consumption, almost twice the expended. This is not a solution, but perhaps a significant step in the right direction.
The experiment is a controlled thermonuclear reaction induced by a pulse from the laser 192. Target is 2 mm ball frozen to a temperature of 18 K, deuterium and tritium, placed in a plastic bag with the inclusion of gold and enclosed in glass. In the process of short-term exposure to the ball with a pulse fuel runs self-sustaining reaction - the synthesis of elements with the appearance of alpha particles and self-heating fuel. In a similar experiment in September last year when applying for a fuel capacity of 10 kJ pulse was fixed return of 14 kJ.
Under the impulse fuel must be highly compressed . In other words it is necessary to comply with three conditions: to create a huge and even pressure on the ball with the fuel inside it to swing enough energy to avoid self-ignition and fuel mixing with elements of the shell. Related Products :
