Another said Tutt did not fire, but admitted noticing Tutt's gun had a discharged chamber.

A revolver with one discharged chamber and a calibre which corresponded with the bullet was found on the floor of her wardrobe."

The atria are the receiving chambers and the ventricles are the discharging chambers.

Propellant atoms are injected into the discharge chamber and are ionized by electron bombardment, forming a plasma.

Thus, there is a strong need for deep understanding of a wide spectrum of the processes taking place in the discharge chamber in order to develop highly effective plasma torches that we have proposed to use as a source of the thermal plasma.

Hall thrusters suffer from very strong erosion of the ceramic discharge chamber by impact of energetic ions: a test reported in 2010 showed erosion of around 1 mm per hundred hours of operation, though this is inconsistent with observed on-orbit lifetimes of a few thousand hours.
