With an electron source (filament) to emit electrons and by drawing them to the anode (vacuum chamber), the plasma is generated and maintained due to electron-neutral gas collisions.
A distortion in the trap geometry is induced by pushing the electron filament tip 1 mm into the volume of the trap, so that it protrudes in as shown in Fig. 10.
The high reaction exothermicity might even generate ionic reaction products, but none were detected when the electron filament was turned off.
Conventional x-ray machines consist of a long tube with an electron emitter, typically a tungsten filament, at one end and a metal electrode at the other.
Viewed through an electron microscope, ebolaviruses appear as long filaments, sometimes branched or intertwined.
The electron beam is supplied with a tungsten filament electron gun, which emits electrons when heated in excess of 2500°C under vacuum [ 77].
Serial images of the stratum radiatum part of CA1 region were collected using Morada CCD camera and iTEM software (Olympus, Munster, Germany) on a Philips CM10 electron microscope (filament voltage 80 kV), aligned and analyzed using Fiji software (http://fiji.sc/wiki/index.php/Fiji).sc/wiki/index.php/Fiji
A typical X-ray tube consists of a cathode (a source of electrons, usually a heated filament) and an anode, which are mounted within an evacuated chamber or envelope.
Cathode ray, stream of electrons leaving the negative electrode (cathode) in a discharge tube containing a gas at low pressure, or electrons emitted by a heated filament in certain electron tubes.
High-resolution transmission electron microscopy (HR-TEM) was performed on a Philips CM30UT electron microscope with a LaB6 filament as the source of electrons operated at 300 kV.
Like a television set, these devices produce electrons from a heated filament sitting inside a vacuum tube.
