Abstract: Radio pulsars are ejected into the halo from the Galactic disk by their large birth velocities. Although the majority of them cease radio emission whilst they are still near the Galactic plane, the halo contains a large population of dead neutron stars that have completed many oscillations in the Galactic potential. The globular cluster system contains many active pulsars and these have been used to constrain the column density of free electrons in the halo. Dispersion of radio pulsars can be used to limit the mass of the halo comprised of free electrons or any other exotic sub-atomic particles postulated to make up the mass of the halo. Recycled pulsars such as the millisecond pulsars have very long lives and may ultimately contribute to our knowledge of the Galactic potential.
