Magnetic field of wien filter
A Wien filter also known as velocity selector is a device consisting of perpendicular electric and magnetic fields that can be used as a velocity filter for charged particles, for example in electron microscopes and spectrometers. It is used in accelerator mass spectrometry to select particles based on their speed. The device is composed of orthogonal electric and magnetic fields, such that p… WebWien Filter General Description This tracking example demonstrates how particles are influenced by static electric and magnetic fields. Protons emitted by an anode move through an electric field of a capacitor and a magnetic field of a current driven horseshoe magnet. Due to the geometry, the magnetic field is perpendicular to the electric field.

Web14 sep. 2024 · If you now slowly increase the strength of the magnetic field, the deflection becomes weaker and weaker until the electrons pass through the filter. The detector registers this and you know that you have found the right balance between the electric and magnetic fields. Figure 8: A particle is not deflected and is detected at the detector. WebWien filter. Wien filters are used to separate charged particle beams by the velocity of the involved species by using orthogonally superimposed magnetic and electric …
