1. An electron beam additive manufacturing system comprising:
an electron beam source;
an x-ray detection sensor configured to generate a waveform corresponding to an amount of x-rays detected by the x-ray detection sensor; and
an electronic control unit comprising a processor and a non-transitory computer-readable memory, the electronic control unit communicatively coupled to the electron beam source and the x-ray detection sensor, and the electronic control unit is configured to:
cause the electron beam source to emit an electron beam such that the electron beam impinges a verification plate,
receive the waveform generated by the x-ray detection sensor in response to the x-ray detection sensor capturing x-rays emitted from the impingement of the electron beam with the verification plate, and
determine a melt performance of a surface material of the verification plate based on the waveform.
