Simultaneous beam position measurements of imager pop-in type I and XGM in the SPB branch of XTD9. (Left) Five discrete steps evaluated out of imager (red dots) and XGM (black dots) position data. Imager position data were linearly shifted with respect to the XGM data for better visualization. (Right) Correlation between imager and XGM position data after XGMD ion signal is settled. The slope of the linear fit is 0.996 with a standard deviation of 0.009. The data source is XTD9 XGM (SASE1), pulse energy at XTD2 XGM was 400 µJ, attenuated to 100 µJ at XTD9, averaged ion signal of XGMDh, date 24 August 2017, wavelength 0.136 nm, XGM with a Xe gas target.
