(DECPOL). This makes it possible to monitor separately the polarisations of the incident and scattered beams, in 3 dimensions.

field magnet 239OXHV21 remain below 2 and 10 daN when the field is perpendicular and parallel to the beam respectively. This magnet can therefore be used at nominal field on SAM.

Atomic Beams lab. The lab was under the nominal direction of J.R. Zacharias who had been, with Norman Ramsey, a student of I.I.

the typical measuring strategy of a three axis spectrometer like IN8. The monochromator selects a beam of neutrons in a narrow energy band. The analyser is positioned to select a scattering direction (related

configuration. Unpolarised neutrons are reflected by the graphite monochromator. The incident neutron beam is polarised by the supermirror bender polariser. For measurement of SF cross-sections, the neutrons
