Abstract

Abstract

Based on the photocathode S-band electron linac, a high-energy (9 MeV) micro-focus CT system named “Jingwei” was built. The focal-point is less than 100 μm, and the 7 h dose fluctuation is as low as 1.6%. An initial imaging experiment was also carried out. The focal spot of the dual-wire image quality meter clearly distinguished the 13D wire with a wire diameter of 0.05 mm, and the CT spatial resolution measured by a test card is better than 10 lp/mm. The electron beam energy of the system is also adjustable from 6 MeV to 18 MeV.
- high-energy micro-focus X-ray source,
- high-energy industrial CT,
