Study of uniformity in X-ray linear array detectors

It shows the outputs of the array detectors both with X-rays without X-rays. It is found that the outputs uniformity is existed under the two situations before. Although the uniformity could be decreased after the offset calibration and gain calibration, it never touches the real point and will affect the quantitative calculations. EGSnrc package is used to compute energy depositions in different thicknesses crystals with different energy X-rays incident. The reasons that cause Cross-talk between crystals are also discussed. The quantitative relations that will be helpful to the improvement of the array detectors and the software revising are also showed. (author)
