Figure 5
Focused beam profiles (a)–(c) obtained using compound lenses. Profiles (f) and (g) obtained using magnetic lenses. Profile (d) for a beam without a focusing lens. Profile (e) of ideal focusing without chromatic aberration. Thick solid lines indicate background levels due to electronic noise and γ-rays. Broken lines are background levels estimated for the defocusing of antiparallel neutrons, depending on the polarization P.
