High brightness electron emitter

Super LaB₆

We commercialized high brightness electron emitter "Super LaB₆".
We started sample supply, trial production, manufacturing and sale.
Due to its low work function, it is possible to obtain higher current density and longer lifetime than LaB₆ of the conventional product.
This product is based on joint development with Associate Professor Hidekazu Murata of Department of Electrical and Electronic Engineering, Faculty of Science and Engineering, Meijo University (Nagoya-shi Tenpaku-ku, Shiogamaoguchi 1-chome 501 telephone +81-52-832-1151).

Features

  • It is an emitter with a low work function compared to LaB₆ based emitter.
  • It is possible to realize current density 10 times or more higher than LaB₆ based emitter.
  • It is possible to realize a lifetime of 10 times or more as compared with LaB₆ based emitters.
  • Even if it is exposured to the atmosphere after use, there is almost no degradion in performance.
