To Control Ionization. 1  Ionization Voltage Typically, 70eV electrons from the filament are used for EI. 2  Emission Current The number of ions produced in unit time is proportional to the current of emitted electrons, i.e., emission current. 3  Ion Source Temperature The ion source is usually used at about 200 oC.
The size and direction of the E-field is independent of the test charge. The test charge is just an imaginary artifice which we use to measure something which is already there. The E-field around a positive charge points always from the charge, and decreases in magnitude with distance r as 2 1Erâ .
