Abstract
The number and the sequence of layers of a tungsten and carbon target changes the energy losses of fast electrons in it. The results of calculations using the GEANT4 and PENELOPE programs agree with each other and show that when passing through a W/C target, electrons lose less energy than in a C/W target. The effect is explained by the redistribution of the deposited energy, which is caused by the reflection of electrons from the interface of materials. An increase in the number of layers leads to a decrease in the influence of the target structure on the distribution of the energy absorbed in it.
