Schematic view on the spacer-gel range measurement setup. Using the three plane laser system indicating the beam line and the isocentre a vial containing the gel sample (inserted in the vial holder) was positioned axisymmetric to the horizontal beam line. In order to minimise effects of lateral scattering of particles the distance from the beam exit to the water column was minimised.
