Hackermen Posted November 11, 2017 Share Posted November 11, 2017 I have a tube (placed horizontally) . Ions are traveling through it. They exit at various angles to the axis of the tube and in different planes. Can I use a magnetic field so that the ions all exit parallel to the axis of the tube, i.e. the horizontal.

studiot Posted November 11, 2017 Share Posted November 11, 2017 Magnetic focusing was traditionally used in cathode ray tubes (CRTS) for televisions, unlike CRTs for oscilloscopes which use electrostatic focusing. Link to comment Share on other sites More sharing options...
