Web10 apr. 2024 · It can be seen that the transverse distribution of the fast electron beam expands with increasing penetration depth owing to its initial divergence. The fast electron beam has a uniform distribution in the region x = 1–50 μ m, while filaments appear after it has penetrated x = 100 μ m into the slice. WebDue to diffraction, a Gaussian beam will converge and diverge from an area called the beam waist (w 0 ), which is where the beam diameter reaches a minimum value. The beam converges and diverges equally on both sides of the …
