CNT Emitter
CNT field emission Emitter
CAT Beam Tech's patented technology, CNT emitter product line with excellent field emission characteristics.
Product Catalog
Carbon nanotube emitters Carbon nanotube emitters are synthesized directly 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 carbon nanotube emitter is not only excellent in field emission characteristics, but also can be manufactured in various forms, making it an optimized product for X-ray sources.
