Figure 7
QENS signal of the empty measurement chamber in a dry (RH = 5%, black) environment. The signal stems from incoherent scattering at the aluminium walls of the chamber and is referred to as background signal herein. The increasing scattering intensity on the positive energy transfer side can be ascribed to the time-independent background signal of the FOCUS instrument. In addition, the signal of the empty measurement chamber in a humid (RH = 82%) environment is shown without (blue) and with (purple) background correction. For clarity, the zero lines for both axes are plotted as well. |
