KGF also allowed the scientists to study the energy spectrum and angular distributions of muons even at very high energies.

The angular distribution of radiated power is given by a general formula (applicable whether or not the particle is relativistic):

However, because they are in the far field, their angular distribution does not change with distance.

Integration of this expression over electron energy gives the angular distribution of the daughter electrons:

Detecting scattered particles through a metal filament gave a good indication of angular distribution but has no sensitivity to kinetic energy.

With information about the velocity, angular distribution, and identity of the scattered species, useful information about the dynamics of the system can be derived.

To enable measurements of angular distributions all those elements are mounted on a rotate able table with the axis cantered at the sample.

For ultrarelativistic particles the latter effect dominates the whole angular distribution.

This breaks down the angular requirement for a seamless cone and therefore broadens the angular distribution.

The electron imager side can also be used to record photoionization cross sections, photoelectron energy and angular distributions.
