Abstract
Certain configurations of ionization sources are described. In some examples, an ionization source comprises an ionization block, an electron source, an electron collector, an ion repeller and at least one electrode configured to provide an electric field when a voltage is provided to the at least one electrode. Systems and methods using the ionization source are also described.
