In gas discharge, why do the negative ions of SF6 gas play a role in hindering the formation of discharge?
In the gas discharge, the negative ions of SF6 gas play a role in hindering the formation of discharge on the one hand, because the average free stroke of ions in SF6 gas is shorter than that of electrons, so the energy obtained is small. On the other hand, when ions collide with molecules, it is easy to lose the original accumulated energy. As a result, the ion has little chance of accumulating enough energy, and its ionization capacity is much lower than that of an electron. When a neutral atom absorbs electrons and becomes a negative ion, the ionization power decreases. Therefore, in gas discharge, negative ions play a role in preventing the formation of discharge.
