Simultaneous beam position measurements for the SASE1 beam at XTD2 and XTD9 XGM. Horizontal (left graph) and vertical (right graph) beam position correlations are shown. The horizontal and vertical slope of the linear fits are 3.8 and 2.5, respectively. Data sources are XTD2 and XTD9 XGMs (SASE1), averaged ion signals of XGMDh and XGMDv chambers, date 15 June 2018, wavelength 0.134 nm, 60 pulses per train, both XGMs with Xe gas targets. The distance between the SASE1 source point and XTD2 and XTD9 XGM is 209 m and 878 m, respectively. |
