Cesium 133 is the element most commonly chosen for atomic clocks. To turn the cesium atomic resonance into an atomic clock, it is necessary to measure one of its transition or resonant frequencies accurately. This is normally done by locking a crystal oscillator to the principal microwave resonance of the cesium atom.

In vacuum tubes and gas-filled tubes, a hot cathode or thermionic cathode is a cathode electrode which is heated to make it emit electrons due to thermionic emission.This is in contrast to a cold cathode, which does not have a heating element.The heating element is usually an electrical filament heated by a separate electric current passing through it. Hot cathodes typically achieve much ...
Installation instructions are excellent. I decided to bypass the ballasts, which brought a bunch of old shop lights back to life. The LED tubes are rated only slightly higher, in lumens, than the 40 watt fluorescent tubes but the 5000k temperature combined with the clear tube gives an amount of light that seems twice the old tubes.
