A quenching gas such as a halogen is used in a GM tube to damp or quench the electron cascade. Recall that the electron avalanche is initiated by incident radiation that the tube was designed to detect. At some point that electron avalanche needs to be damped to "reset" the tube so it can react to another incident. Quenching gas does this.

Avalanche breakdown is a phenomenon that can occur in both insulating and semiconducting materials. It is a form of electric current multiplication that can allow very large currents to flow within materials which are otherwise good insulators. It is a type of electron avalanche.

The Avalanche process occurs when the carriers in the transition region are accelerated by the electric field to energies sufficient to free e- h pairs via collisions with bond electrons.
