Positrons Using The HRRL

The purpose of this research is to evaluate the veracity of a positron beam line using the quad triplet method to collect positrons produced when a 10 MeV electron beam impinges on a 1.25 mm thick Tungsten target.

Positron Beam Properties

Tungsten thickness

The optimal Tungsten target thickness to produce positrons using a 10 MeV incident electron beam appears to be 1.25 mm.
