Proposals have been made for the introduction of magnetic electron beam delays in between the undulator modules of a long sectional FEL undulator - these can be used for the generation of trains of FEL pulses which can individually be shorter than the FEL cooperation time or to greatly improve the temporal coherence of the FEL output compared to the nominal SASE configuration. This paper comprises a feasibility study of the application of these techniques to a future SwissFEL hard X-Ray beamline. Three-dimensional simulations are used to investigate the potential photon output.
