Abstract
A betatron is provided for producing pulses of accelerated electrons, particularly in an x-ray testing device, comprising at least one main field coil, one expansion coil for transferring the accelerated electrons to a target, and one electronic control system of the expansion coil for applying an expansion pulse to the expansion coil. The electronic control system of the expansion coil is designed such that the time of the expansion pulse for adjusting the final energy of the electrons is variable relative to the main field.
Claims10
A betatron for producing pulses of accelerated electrons in an X-ray inspection device, the betatron comprising:
- at least one primary field coil;
- an expansion coil for transferring the accelerated electrons onto a target;
- and
- an electronic control system for the expansion coil configured to apply an expansion pulse to the expansion coil, the electronic control system for the expansion coil configured such that the time of the expansion pulse relative to the primary field is variable in order to set a final energy of the electrons.
An X-ray inspection device for security screening of articles, the device comprising:
- a target for generation of X-rays;
- an X-ray detector;
- an analysis unit;
- and
- a betatron comprising:
- at least one primary field coil;
- an expansion coil for transferring the accelerated electrons onto a target;
- and
- an electronic control system for the expansion coil configured to apply an expansion pulse to the expansion coil, the electronic control system for the expansion coil configured such that the time of the expansion pulse relative to the primary field is variable in order to set a final energy of the electrons.
