  "abstract": "Inverse Low Gain Avalanche Diode (iLGAD) sensors developed at the Paul Scherrer Institute (PSI) in collaboration with the Fondazione Bruno Kessler (FBK) have demonstrated an excellent Signal-to-Noise Ratio (SNR) and Quantum Efficiency (QE) in the soft X-ray range. In the current batch, single-photon detection is achievable at 400 eV with an SNR > 5, while the QE surpasses 85 % at 250 eV. Combined with the high frame rates of CMOS readout ASIC, iLGAD sensors make the hybrid pixel detectors excellent candidates for time-resolved magnetic Small Angle X-ray Scattering (mSAXS) experiments in the soft X-ray energy range. In this contribution, we evaluated ILGAD sensors bump-bonded to 25 μm pitch charge-integrating MÖNCH chips at a laser-driven soft X-ray source. During the experiments, we measured energy-dispersed radiation between 600 eV and 1500 eV. These measurements were performed for the iLGAD sensor, as well as for the standard silicon sensor. Using the high-precision electronic trigger of the X-ray source, we were able to synchronise the detector with the X-ray source delivering few-picosecond pulses and optimise the timing parameters for the acquisition. Finally, we successfully performed the mSAXS experiment probing the magnetic domain pattern of a FeGd heterostructure, demonstrating better performance than a MÖNCH detector with a standard silicon sensor. ILGAD sensors achieved a significantly higher photon detection efficiency and, consequently, a higher sensitivity compared to standard silicon sensors under the same conditions, particularly for the lower-energy Fe L3 edge.",
