The sample position on I15-1 is defined in the images below These depict a standard beamline setup, however the position of the detector and beamstop can me changed along the z-axis to optimise Qmin for a given experiment where necessary. The y stage has a travel range of 500 mm, with ca. 170 mm below the beam position and ca. 330 mm above. The x stage has a travel range of ca. 125 mm. With the sample stage set to x = 0 (furthest back), there is a distance of 420 mm between the sample stage and the beamstop arm. The beamstom arm is located ca
