[en] At the ELSA facility at Bonn a photon beam with a high duty cycle up to energies of 3.3 GeV is available. In this energy range the large solid angle detector SAPHIR enables us to investigate the strangeness photoproduction starting from threshold. SAPHIR has already achieved results for the reactions γ+p→K⁺+Λ and γ+p→K⁺+Σ⁰. This work investigates the possibilities to measure the related reactions γ+n→K⁰+Λ and γ+n→K⁰+Σ⁰ at a deuteron target and to measure the reaction γ+p→K⁰+Σ⁺ at a proton target. For the first time the Σ⁺ polarisation has been measured. With an cross section 10 times smaller compared to the kaon hyperon reactions, the photoproduction of the Φ(1020) meson can be investigated with the SAPHIR detector too. First reconstructed events are shown. (orig.)
