We discuss the present status and the prospects of SpinEcho SmallAngle Neutron Scattering (SESANS) against the background of the available expertise and the neutron source PIK at PNPI (Gatchina). Two options for SESANS instruments are reviewed: (1) monochromatic with πflipping permalloy foils and (2) with adiabatic radio frequency spin flippers in a white beam, combined with timeofflight data collec tion. A software tool for quantitative prediction of the technical properties of option (2) is developed. For both options, we show that a SESANS instrument which can compete with instruments elsewhere, is realistic. For option (2), we suggest a perspective of spinecholength range such that neutron interference experiments become feasible.
