Rationale for creating detonation CO2 laser for radioactive surface decontamination
Keywords:spark discharge, pre-ionization, current-conducting channel, lasers, detonation, decontamination, laser radiation, voltage.
The laser decontamination method is based on the evaporation of oxide films under the influence of radiation. With the evaporation mechanism, laser radiation should heat the upper layer of the film to the boiling point during the pulse and evaporate it. It is relevant because of the growing environmental requirements in the world, which makes it possible to create a compact, energy-efficient laser installation. Unlike existing energy-efficient laser units, the detonation laser system will significantly affect and quickly decontaminate radioactive surfaces due to the evaporation of oxide films under the influence of radiation. Detonation technologies are critical and can be used for pulse detonation systems, such as pulse detonation engines, detonation lasers, magnetohydrodynamic generators with detonation combustion of fuel, volume explosion initiation systems. The introduction of these systems in armaments and military equipment can substantially change the scope of their application. The average laser power can exceed 100 kW and above. At the same time, the use of the mixture as a power source makes the system not only compact, but also light in weight with respect to the existing similar systems. The wavelength will be 10.6 μm due to radiation in the far infrared region. That is, combined power plants will provide not only actuation, but also electric power supply of machines. This will allow the creation of power detonation units with a periodic initiation frequency of at least 100 Hz, which will work on a liquefied mixture and insignificant use of oxygen in the incendiary portion.
