UMFX 3 has a hollow cathode configuration. The hollow cathode is formed by making an axial aperture at the cathode. This configuration works as point-like electron beam-target pulsed x-ray source. Emission of x-ray is a pre-breakdown phenomenon. The x-ray spectrum is dominated by emission. The total energy emission from the source can be estimated from the area under the x-ray signal. UMFX 3 possesses 0.1 % high efficiency of x-ray production and 18 mGy of average dosage per x-ray pulse. X-ray radiography of small biological sample is demonstrated.
