Description:
X-ray tubes adopted into Bottling Line Controls used solid tungsten Filaments. 'Heater' is a common synonimous of Filament.Tungsten has a high work function, and there are other metals which are much more suitable in this respect, like Caesium, whose work function is 1.6 eV.nnA tungsten Filament has to be operated at about 2 700 °C, like in common light bulbs.The amount of heat thrown out by any hot object increases with the fourth power of its temperature, meaning that a huge power i
