Analysis of the expected AGIPD detector performance parameters for the European X-ray free electron laser

A review of the parameters of the AGIPD detector planned to be used on the SASE 1 and SASE 2 beamlines of the European XFEL is presented. For both Coherent X-ray Diffraction Imaging (CXDI) and X-ray Photon-Correlation Spectroscopy (XPCS), the required detector noise level and dynamic range are evaluated from signal and background simulations on a per instrument basis. A worst case scenario of accumulated dose is computed in order to evaluate the required detector radiation hardness. Finally, acknowledging a mismatch between pixel size requirement and technological feasibility in the case of XPCS, the possibility to aperture the pixel in order to match the size requirement is presented and discussed.
