    Abstract: The subject of the invention is a procedure for manufacturing a neutron-guiding flat surface of low waviness in the course of which a thin plate coated by a material suitable for neutron reflection, advantageously of multilayered structure, is glued onto a significantly thicker carrier surface. The procedure is characterised by placing the thin neutron-reflecting plate onto a base surface of low flatness, typically of the order of magnitude of 10 -5 radian, advantageously onto a vacuum table, so that the thin plate lies on the base surface with the neutron-reflecting coating facing the base surface, then the thin plate is positioned on the base surface by means of applying reclining contact points formed along the base edge determined by the size of the thin plate, the thin plate is fixed onto the base surface by means of vacuum suction, then the reclining contacts are removed and a glue is attached to the upper surface of the fixed thin plate which displays low absorption capacity to neutrons and retains its binding strength in the presence of incident neutrons, then the thick carrier plate is stuck to the upper surface of the thin plate by moving the thick plate back and forth thus providing the homogeneous dispersion of the glue, then the thick carrier plate is fixed onto the base surface by reclining points and the binding process of the glue is accelerated by a known and appropriately selected procedure of binding acceleration, then finally the glued plates are removed from the base surface by undoing the reclining points.
