摘要
A reflectron for use with a mass spectrometer that focuses ions having different energies contains a conductive end cap that is electrically connected to a first voltage. A conductive surface is electrically isolated from the end cap and connected to a second voltage. This conductive surface cooperates with the conductive end cap to establish an inner region in which a non-linear electric field exists. As a result, ions having different energies enter and exit the inner region at a common opening and, when within the inner region, are reflected without penetrating past the conductive surface.
