COMPANYOVERVIEW
New X-ray New Paradigm
With years of experience and original ideas in Carbon nanotube technology,
CAT Beam Tech brings the new X-ray to paradigm shift the 100 years old X-ray technology.
CAT Beam Tech’s patented digital X-ray tube produces X-rays based on directly grown
Carbon nanotube(CNT) emitter with excellent resolution, low radiation dose and long-lasting durability.
In particular, CNT based digital X-ray tube helps in developing the compact and miniaturized X-ray systems
that can produce high-resolution X-ray images and give the next level of X-ray experience.
RESEARCH OVERVIEW
Nanomaterial
CAT Beam Tech holds the intellectual property around both the CNT emitter and the method of manufacture. With technological know-how in designing and manufacturing production systems, the CNT emitter can be grown directly on various substrates based on customers need and has excellent field emission characteristic.
Digital X-ray
CAT Beam Tech's digital X-ray source has minimal focal spot size due to the smaller electron emission area, and it is easy to synchronize with the movements of heart and lungs by digital pulsed operation. It can provide an improved solution to variety of fields compared to conventional analog filament based tube, and is applied to a variety of systems from industrial to medical applications.
Technology
Directly grown carbon nanotube
Carbon nanotube(CNT) emitters are synthesized through the process of directly grown CNTs on metal or silicon substrates by decomposing mixed gases(C₂H₂, NH₃) with energy such as heat, electric field, and plasma. CAT Beam Tech's directly grown CNT emitter is optimized for X-ray electron emission sources as it has excellent field emission characteristics and can be manufactured in various forms.

Technology
CNT Electron gun (E-gun)
We have a wide range of E-guns based on cold-electron-type electron guns with carbon nanotube emitters and hot-electron-type electron guns with filaments. In particular, the CNT electron gun is a triode type E-gun with integrated focuser and has lowest gate current loss of 5%~15%.
