Fig. 3From: Evaluation of CCD cameras for beam profile monitoring with high intensity particle beams traversing gasesThe light intensity recorded by the camera (Signal) is shown versus the distance of the aperture (X, in Fig. 1) to the tungsten-strip. The concept of the measurement is described in the text. The constant intensity value for distances shorter than 143mm corresponds to a solid angle of 3.84·10−3 sr. In red the \(I(x)=I_{0} \cdot x_{0}^{2}/x^{2} + U\) fit function is plotted. The blue line is the constant level of intensity before the point of reduction. The smaller plot inside the main plot shows a wider distance and signal range in the way it is expected to evolveBack to article page
