1. First Steps XFEL S2E with CSRtrack Convert elegant particlefile upstream of BC-3 into CSRtrack input CSRtrack results

2. CSRtrack 3D self consistent tracking code beam is modeled by macroscopic sub bunches sub bunches are 3D gaussian charge distributions sub bunch, generates fields, tracked self consistent sampling bunch, tracked only

3. Elegant longitudinal phase space with 3rd order polynomial fit

4. Longitudinal Histogram and Sum of Sub-Bunches

5. Longitudinal Phase Space Downstream BC-3

6. Horizontal Phase Space Downstream BC-3

7. Current vs. Longitudinal Bunch Position

8. Horizontal Slice Emittance vs. Longitudinal Bunch Position [um]

9. Horizontal Position Slice Offset vs. Longitudinal Bunch Position

10. Transverse offset in sigma vs. Longitudinal Bunch Position

11. Optical Mismatch Parameter vs. Longitudinal Bunch Position
