ABSTRACT:
A time of flight (TOF) mass spectrometer includes an ion source which has an extraction lens. The extraction lens has an element with an aperture. The aperture extends through the element to form a through-channel. In use, ions may pass from one side of the element to the opposite side of the element by passing through the through channel. The through channel has a length which is equal to or greater than {fraction (8/10)} of a diameter of the aperture.
