Among the possible applications of synchrotron light sources, time resolved experiments are interesting for many users and usually require special operation modes. However, the time structures of X-ray pulses generated by a synchrotron light source are usually limited to integer times of the RF period, which is typically several nanoseconds (e.g., 2 ns RF period time corresponding to 500 MHz RF frequency). Here, we propose a novel scheme to take advantage of transverse deflecting cavities and over-stretching conditions of the higher harmonic cavities to ensure the transverse and longitudinal tunability of the twoμbunches in the same RF bucket. By applying this scheme, two X-ray pulses with tunable transverse displacement (mm level) and time delay (hundreds of ps level) can be provided to the scientific users for their X-ray pump X-ray probe experiments or X-ray probe X-ray probe experiments. The key setting parameters to generate the two X-ray pulses are given here. The classical "single-bunch" instabilities under the over-stretching conditions were also studied and presented.
