“…For the specified cell the maximum acceptance is A(β 0 = 0.2 m) ≈ 58 µm (see figure 3). To obtain the required small β-functions, a low-β insertion consisting of four additional quadrupole magnets (blue in figure 4), formerly used at CELSIUS [48], was installed in the drift space in front of and behind the target. The quadrupole magnets are arranged in a doublet structure (DF-FD), where the D and F magnets are powered by separate power supplies.…”

The paper describes the commissioning of the experimental equipment and the machine studies required for the first spin-filtering experiment with protons at a beam kinetic energy of 49.3MeV in COSY. The implementation of a low-β insertion made it possible to achieve beam lifetimes of τb=8000s in the presence of a dense polarized hydrogen storage-cell target of areal density dt=(5.5±0.2)×1013atoms/cm2. The developed techniques can be directly applied to antiproton machines and allow for the determination of the spin-dependent p¯p cross sections via spin filtering

The implementation of a low-β insertion made it possible to achieve beam lifetimes of τ b = 8000 s in the presence of a dense polarized hydrogen storage cell target of areal density dt = (5.5 ± 0.2) × 10 13 atoms/cm 2.

“…The WASA detector [19] was, until June 2005, an integrated part of the CELSIUS storage ring. In the measurements presented here, a target of deuterium pellets [20,21] was used, designed for a 4π detector geometry and high luminosity.…”
