High brightness electron emitting device "Super LaB₆"
Sample supply, trial manufacture, manufacture, sales started.
It is possible to obtain higher current density and longer life than the conventional LaB₆.
This product is based on joint development with Professor Hidekazu Murata Department of Electrical and Electronic Engineering, Meijo University School of Science and Engineering(Nagoya-shi Tenpaku-ku, Shiogamaoguchi 1-chome 501 telephone +81-52-832-1151).
Features
- 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.
