Mathematical modelling of heating of homogeneous metal targets with a focused electron beam

The problem of heat distribution in metal materials irradiated with sharply focused electron beams in the absence of heat exchange between the target and the external medium is considered with mathematical modeling methods.

Description
Summary:The problem of heat distribution in metal materials irradiated with sharply focused electron beams in the absence of heat exchange between the target and the external medium is considered with mathematical modeling methods. For a quantitative description of energy losses by probe electrons a model based on a separate description of the contributions of absorbed in the target and backscattered electrons is used. This method is applicable to a wide class of solids and a range of primary electron energies. Some modeling results are illustrated for different metal materials.
