Fig. 1From: Evaluation of CCD cameras for beam profile monitoring with high intensity particle beams traversing gasesSchematic drawing of the optical setup. The calibrated light source Wi 17G (A) was used to calibrate the sensitivity of the detection system consisting of a lens (C) and a camera (D). The wavelength of the measurement was determined by an optical bandpass filter (B). The light was attenuated by up to two neutral density filters (B’). The solid angle of the imaging optics was measured with a 10.0mm diameter aperture (X) as described in the text. This aperture was removed for all other measurementsBack to article page
