摘要： An inspection radiation source is provided. The inspection radiation source includes an electron accelerator for generating an electron current, and a target for the electron current including a first part and a second part. This first part is configured to be at least partly exposed to the electron current on an impact area having a first width in a direction substantially perpendicular to the electron current, and inhibit propagation of the electron current. The second part has a second width in the direction substantially perpendicular to the electron current, the second width of the second part being smaller than the first width of the impact area, the second part being configured to be at least partly exposed to the electron current, and generate inspection radiation by emitting X-rays in response to being exposed to the electron current.

摘要： The invention relates to equipment (1) for the radiography of a load (11) moving relative thereto, the radiography equipment comprising a source (2) for emitting pulses (16) of divergent X-rays, a collimator (4) for the source for delimiting an incident x-ray beam (22), and sensors (8) for receiving X-rays, which are aligned with the incident beam so as to collect the X-rays after the latter have passed through the load and generate raw image signals. The equipment includes a reference block (6) comprising the intermediate x-ray sensors (28) which are to be located within the incident beam, between the source and the load, so as to be irradiated by at least two separate angular sectors of the incident beam, and which are to output separate reference signals corresponding to each angular sector to be used in the conversion of the raw image signals into a portion of a radiographic image. The invention also relates to a corresponding method.
