Jet chambers for the measurement of charged particle tracks.

The whole tracker is immersed in a powerful magnetic field so the particle tracks are curved; from the curvature, the momentum can be deduced.

The result is a circle with a radius independent of the emission point along the particle track.

After exposing and developing the plate, single particle tracks can be observed and measured using a microscope.

The particle track is typically bent into a circle using electromagnets.

It is also a crucial process in forming particle tracks in a cloud chamber.

On the other hand, the higher concentration of deposited energy can cause more severe damage to any microscopic structures near the particle track.

This energy limit is meant to exclude secondary electrons that carry energy far from the primary particle track.

Since the LET varies over the particle track, an average value is often used to represent the spread.

The photons and some of the higher energy electrons, called delta rays, carry energy far from the particle track before depositing it as ionization or excitation.
