Ionization Cooling - Longitudinal Cooling

Longitudinal Cooling

The technique can be adapted to provide longitudinal as well as transverse cooling by using a dipole magnet as a dispersive prism to divide the particles by energy, and then passing the resultant "rainbow" beam though a tapered wedge of cooling material. Thus, faster particles are cooled more and slower particles are cooled less. A simple way is to fill the dipole itself with cooling material, so that more energetic particles following a larger orbit pass are cooled more.

Famous quotes containing the word cooling:

    As a bathtub lined with white porcelain,
    When the hot water gives out or goes tepid,
    So is the slow cooling of our chivalrous passion,
    O my much praised but-not-altogether-satisfactory lady.
    Ezra Pound (1885–1972)
