The paper presents the simulation of a complex of reserch with ultracold neutrons at the reactor PIK (Gatchina, Russia). The complex is being built on the basis of a high-intensity source of ultracold neutrons at the channel GEK-4. A Monte Carlo model has been developed, which includes a source, a neutron guide system and an experimental setup for search for the electric dipole moment of a neutron, taking into account their real location in the main hall of the reactor. Using the developed computer model the density of ultracold neutrons in the setup was obtained, which is 200 <sup>-3</sup>. It is 50 times higher than at the source at the Institut Laue-Langevin (Grenoble, France). This density will allow to achieve a sensitivity of measurements in the experiment of 1·10<sup>-27</sup> е·cm/year.

`Acceptance' diagrams are used to describe the beams produced by curved segmented (`focusing') monochromators in the kinematic approximation. This semi-analytic semi-graphical method leads to a complete description which is readily visualized in terms of instrument variables. Focusing both in and perpendicular to the scattering plane is considered. Clear relationships are identified between instrument dimensions and the beam produced. The description is directed towards neutron scattering instruments but the formalism should also apply to photons and electrons. It is demonstrated that a monochromator curved both in and perpendicular to the scattering plane (`double focused') on either a straight or curved neutron guide tube from a reactor source can produce a beam of comparable flux to that achievable at the reactor face. Such a beam has spatial dimensions comparable with modern single-crystal samples for inelastic scattering and could thus provide spectacular signal and, even more interestingly, signal to noise ratios for both elastic and inelastic single-crystal spectrometers.
