WebIonization chambers operate at a low electric field strength, selected such that no gas multiplication takes place. The ion current is generated by the creation of "ion pairs", consisting of an ion and an electron. The ions drift to the cathode while free electrons drift to the anode under the influence of the electric field. Web4 mei 2024 · The gas becomes ionized by interactions with electrons and gas molecules within the chamber, forming a plasma (Figure 7). The plasma is then accelerated through a series of at least two highly charged grids, leading to a primary beam of oxygen ions. bitmap brothers speedball
