Experimental study of the scattering of $7.4$-MeV electrons intersecting a foil at an angle of $10^\circ$–$45^circ$ to its surface

Angular distributions of electrons intersecting $40$- and $120$-$\mu$m aluminum foils and a $60$-$\mu$m copper foil have been measured. Electrons have been injected from a microtron with a particle energy of $7.4$ MeV. The effect of the material and thickness of a foil, as well as of the direction of injection, on the spatial distribution of passed particles has been analyzed. The measurements have shown that the intersection of the foil at small angles to its surface not only increases the transverse dimensions of the beam but also changes the direction of its motion.
