Schematic view of QGS setup using multi-line TDI, the time spectra obtained and their fitting curves. (Top) Schematic view of the experimental QGS setup using multi-line TDI is shown along with the energy spectrum of the gamma rays. Time spectra of the gamma rays: (a,b) obtained from calibration measurements in the forward direction from emitter 1 (α-Fe foil with H‖h _σ ) and emitter 2 (α-Fe foil with H‖h _π ); (c) obtained from the QGS experiment for glycerol at 237.5 K at 14 nm⁻¹ (calculated time spectrum based on assumption of the results of the calibration measurements with both emitter 1 and emitter 2, which are also shown in the upper part as a green line); (d,e) obtained from the QGS experiments for glycerol at 237.5 K at 14 nm⁻¹ and 31 nm⁻¹, respectively, in the stable emitter condition; (f) obtained from the forward-scattering experiments with two α-Fe emitters in the driving condition; and (g,h) obtained from the QGS experiments for glycerol at 255 K at 14 nm⁻¹ and 31 nm⁻¹, respectively, in the driving emitter condition. In addition to these time spectra, fitting curves are also shown. Vertical bars denote the standard deviations of the measured points.
