Figure 5
Measured rocking DCM curve (open circles). The filled markers denote the output of the phase-sensitive detection (PSD) system using three different amplitudes of the excitation or dither signal (squares: 50 mV; triangles: 35 mV; diamonds: 25 mV). The output of the PSD system is the product of the measured signal amplitude and the sign of the phase difference between the dither signal and the measured ion chamber AC signal. The thick solid line shows the differentiated theoretical rocking curve that was scaled to the result obtained with a dither signal with an amplitude of 50 mV.
