Patent number: 11728125Abstract: There is provided an ultrafast electron diffraction apparatus including: a photoelectron gun configured to emit an electron beam; a bending portion for emitting the electron beam emitted from the photoelectron gun by changing a travel direction of the electron beam by a predetermined angle; and a sample portion including a sample to be analyzed by the electron beam emitted from the bending portion. The electron beam reaches the sample portion in a state that a pulse of the electron beam is compressed and the timing jitter between the pumping light and probe electron pulse is completely reduced as the travel direction of the electron beam is changed by the predetermined angle through the bending portion.Type: GrantFiled: December 18, 2020Date of Patent: August 15, 2023Assignee: Korea Atomic Energy Research InstituteInventors: Young Uk Jeong, Nikolay Vinokurov, Hyun Woo Kim, Ki Tae Lee, Kyuha Jang, Inhyung Baek

Patent number: 9502166Abstract: A variable-period permanent-magnet undulator which is applicable not only to a planar undulator but also to a helical undulator, in which permanent-magnets and ferromagnetic substances are alternately arranged, and the ferromagnetic substance interposed between the permanent-magnets is saturated to thus enable the magnets to be effectively spaced apart from each other by the repulsive force between the permanent-magnets, thereby adjusting the period of the magnetic field in an easy and precise manner.Type: GrantFiled: December 26, 2012Date of Patent: November 22, 2016Assignee: KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Young Uk Jeong, Ki Tae Lee, Seong Hee Park, Shang In Shin, Kyuha Jang, Jeong Ho Moon, Nikolay Vinokurov

Patent number: 9337603Abstract: This specification relates to a terahertz pulse generator capable of generating ultra-short terahertz pulses by use of electron beams transported through a plurality of foils. The plurality of foils in a shape of disc are arranged in an overlapped state and form a conical shape that diameters of the disc-shaped foils sequentially decrease along a direction that the electron beam is transported. Coherent radiation, which is generated as the ultra-short electron beam is transported through the foils in respective spaced gaps of the foils, is propagated toward the outside of the disc-shaped foils and gathered with forming a conical wave surface at edges of the disc-shaped foils. This may result in enhancement of generation efficiency of the terahertz waves.Type: GrantFiled: May 14, 2013Date of Patent: May 10, 2016Assignee: KOREA ATOMIC ENERGY RESEARCH INSTITUTEInventors: Nikolay Vinokurov, Young Uk Jeong
