Conventional layouts for (a) the polarized focusing beam projected onto the detector at the downstream end (Oku et al., 2007View full citation) and (b) the polarized non-focusing beam projected onto the detector at L2 = 1835 mm; new layouts for (c) the loose-focusing beam and (d) the tight-focusing beam; and conceptual drawings of the focusing and polarization of (e) the loose-focusing beam and (f) the tight-focusing beam. In the conventional layout for the unpolarized non-focusing beam, the supermirror polarizer in (b) is removed. The dashed lines in (e) indicate the trajectory of negative spin-polarized neutrons. The yellow lines and ellipse in (f) show the virtual lens, illustrating the combined focusing action of the preexisting and extended lenses.
