What is Hohlraum?

and Hohlraum is a hollow cylinder -shaped device used to focus and control radiation. Named for the German word for the hollow area, the device distributes radiation evenly inside its walls and heats a small piece of fuel in the center. It can be as small as a paper clip or a pencil rubber, or it may contain a nuclear weapon cover. To simulate nuclear explosions on a miniature scale or with lasers to produce energy, when a small fuel sample, such as deuterium or tritium is improded, can be used Hohlraum capsules that can be used to simulate nuclear explosions. A small hole in the container can be used to measure escape radiation and how it behaves at temperatures inside the interior space.

The focus of a strong radiation source as a laser towards the inside of Hohlraum can create a fusion reaction contained inside. The created X -rays are absorbed and symmetrically radiated inside to check the stability of the system during the experiment. This stability allows spherical explosions to receive PKRAJKA, which helps to conduct experiments accurate and contain intensive reactions. Hohlraums can be used during fusion and fission reactions and are the central point of the nuclear weapon for both primary reactions and for secondary atomic reactions.

Often made of lead is built Hohlraum to contain a small ball capsules of fuel. Laser rays are directed through the opening at the end of the part, react with the inner walls and produce X -rays. These X -rays are continuously diverted between the walls and raise the temperature until it is high enough to ignite the fuel. The unfavorable heating of the interior will prevent the energy from concentrating the energy on the laser pellet precisely. Sometimes a thin layer of foam is used as an inner lining to make heat and spread the X -rays more evenly.

reaction inside the cavity also compresses the fuel pellet deuteria, tritium neboberylium andIt warms up to a temperature that is greater than the sun temperature. With a mere hydrogen and helium, temperatures can rise to millions of degrees inside Hohlraum. Scientists think that such reactions can be used as an energy source. Hohlraums absorb so much lasers energy that computer simulations performed before experiments do not show how well absorption occurs. However, in order to create a significant amount of energy, the reactions that are carried out in laboratories would have to occur several times every second for a constant flow of energy.
