Passage of an Intense Relativistic Electron Beam Through a Cusped Magnetic Field

We present results of the injection of a high-intensity, high-current, relativistic electron beam into a cusped magnetic field. ${10}^{14}$ electrons are passed through the cusp. Prelimary observations indicate that these electrons produce a "cloud" of relativistic electrons gyrating in a magnetic field and having a small ratio of translational to rotational energies.
