(a) The cross-section diagram of the compact Ar-scintillation monitor. (b) Photograph of the actual device.
(a) Diagram of the experimental setup at CHESS F3 and A2 beam lines, (b) the diagram of the electronics layout: The top and bottom PIN diodes are connected to two Stanford Research SR570 current amplifiers followed by a 24-bit ADC and the data acquisition personal computer.
(a) Normalized intensity measured with the Ar- scintillation monitor (red) in comparison with the ion chamber intensities. The X-ray intensity was reduced by closing the horizontal slit aperture. (b) Linear dependence between the ion chamber and the Ar-scintillation monitor responses.
(a) Top and bottom signals from the Ar-scintillation BPM (blue and red) and the X-ray position from D/S (black). (b) The measured beam position as a function of Z-stage height (dots) with the linear fit (red line).
