Hence an electron avalanche is created as shown in fig.7.4.

The space charge created by the electron avalanches gives rise to an additional electric field.

When the electric field is strong enough, it can lead to what is known as electron avalanche.

See Electron avalanche for further description of these mechanisms.

The phenomenon of the electron avalanche was discovered by him, and is known as the Townsend discharge.

Electron avalanches are essential to the dielectric breakdown process within gases.

Both positive and negative coronas rely on electron avalanches.

It is a type of electron avalanche.

The electron avalanches leave behind positive ions, so in time more and more space charge is building up.

Streamers are electron avalanches, each one typically lasting only a few nanoseconds.

This creates what's called an electron avalanche.

The photons serve to ionize other atoms, maintaining the creation of electron avalanches.

The limit to the multiplication in an electron avalanche is known as the Raether limit.

An electron avalanche happens between two unconnected electrodes in a gas when an electric field exceeds a certain threshold.

The light is focused onto the photocathode of a photomultiplier tube that triggers an electron avalanche.

As the applied voltage is increased, the free electrons carrying the current gain enough energy to cause further ionization, causing an electron avalanche.

Electron avalanches and breakdown in gases.

In comparison, no such imaging has been reported with the electron avalanche mode of the GDD yet.

The electron avalanche may be what triggers lightning, as well as produce gamma radiation, Fishman said.

Air leaking into the tube introduces oxygen, which is highly electronegative and inhibits the production of electron avalanches.

Above the breakdown field, the number of electrons starts to grow exponentially, and an electron avalanche (Townsend avalanche) forms.

The ion pairs gain sufficient energy to ionize further gas molecules through collisions on the way, creating an electron avalanche of charged particles.

By undergoing inelastic collisions closer and closer to the curved electrode, further molecules are ionized in an electron avalanche.

In a strong external electric field this electron creates an electron avalanche in the direction of the electric field lines.

These electron avalanches (Townsend discharges) create ionized, electrically conductive regions in the air near the electrode creating the electric field.
