Electron impact ionisation occurs in a stainless steel chamber (Figure 2) at a pressure of less than 6 × 10−7 mmHg (i.e. vacuum conditions) achieved by means of a diffusion oil pump or a turbo-molecular pump. At 2000°C by thermoelectronic effect, electrons emitted by a rhenium filament are accelerated to the anode by a 5–100-V potential difference
