Abstract EN
Small tip-type CNT emitters with the diameter of 0.8 mm were fabricated for miniaturized X-ray tubes.
The CNT emitters were prepared by dropping CNTs and silver nanoparticles on a flat surface of a W metal tip followed by annealing at 800°C for 2 h under vacuum.
The CNT emitters exhibit good field emission properties with the threshold electric field of 1.15 V/μm and the field enhancement factor of 12,050.
CNTs were well attached to a flat W tip surface without coating on the side plane of the tip, and thus beam divergence could be minimized.
Consequently, a miniaturized X-ray tube with the inner diameter of 5 mm was successfully demonstrated using the tip-type CNT emitter.
