▎ 摘　　要

NOVELTY - The tube has an anode assembly provided with an anode target and an anode handle. The anode target is sealed with a vacuum glass tube. A cathode assembly is provided with a cathode head, a cathode cover, a glass core post and a cathode base. The cathode head is covered on ends of large and small rectangular holes. USE - High efficiency graphene cathode-ray tube for use as an X-ray tube. ADVANTAGE - The tube has high pressure resistance, better stability, better control electronic emitting quantity, prolonged service life and wide application range. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a high efficiency graphene cathode-ray tube.
