Study On Character of Backstreaming Ions Source

  • Plasma could be produced when intense electron beams striking on converter target materials, such as Ta. The beam space charge may draw an ion current out of the plasma, which could substantially affect the final focus of beam on the target. This is called backstreaming ions effect. Since focus-spot is a key point for good radiography in X-ray machine research, the backstreaming ions effect gets much concerns. Based on our analyses, it is believed that generally the backstreaming ions are mainly from thermal desorption of contaminant on the Ta target surface. The ion emission is restricted by the space-charge effect, not by the ions source power.

Abstract: Plasma could be produced when intense electron beams striking on converter target materials, such as Ta. The beam space charge may draw an ion current out of the plasma, which could substantially affect the final focus of beam on the target. This is called backstreaming ions effect. Since focus-spot is a key point for good radiography in X-ray machine research, the backstreaming ions effect gets much concerns. Based on our analyses, it is believed that generally the backstreaming ions are mainly from thermal desorption of contaminant on the Ta target surface. The ion emission is restricted by the space-charge effect, not by the ions source power.
