A history of the development of time-resolved diffraction experiment on the synchrotron in Novosibirsk INP started since 1975. There are two factors, which lies in the fundament of all time resolved experiments: 1) a powerful insertion devices and X-ray optic provided high intensity of the synchrotron radiation, 2) fast position sensitive and area detectors quickly collected diffraction data. There is no limits for improving the first one, but it will be a lot of problem with detectors, when you will try to do diffraction experiment with time resolution less then micro second. We think that it is impossible to use traditional diffraction scheme for the experiments in the nano second scale.

For the diffraction experiment with nano second time resolution we propose new scheme in which will be used the fast electron beam scanning in the ondulator. The scanning will be made by fast correctors of the electron beam trajectory in the ondulator only. The electron trajectory will not disturbed in the other part of the storage ring. New detector will be developed for this experiment, which will be synchronize with correctors.

The prototype of this experiment was realized at storage ring VEPP-3. The influence of the fast corrector on the behavior of the electron beam and synchrotron radiation was investigated. The prototype of new detector was used in this experiment.
