Abstract
A soft X-ray generator comprises an electron gun and an anode which are disposed in individual vacuum containers, respectively but are interconnected by a conduit provided with an electron lens so that an electron beam generated from the electron gun is guided through the conduit on the anode in a focused form, thereby emitting soft X-rays from the surface of the anode.
