Summary: In this study, a simple and robust method of single-event processing based on the substitution of the original cluster of pixels with an isotropic Gaussian function is introduced. The proposed method offers better filtering of noise power spectrum and allows for sub-pixel resolution. The performance of this method is compared to other standard techniques and shows the best results in a simulated realistic scenario.

Summary: This article presents the calibration process of the HEPS-BPIX hybrid pixel detector, introducing precise and fast algorithms to study threshold digital to analog converters' performance and reduce threshold dispersion. The temperature dependence of silicon pixel module noise was also explored, resulting in a decrease in the minimum detectable energy threshold to 0.83-4.36 keV at 5 degrees C.

Summary: Hybrid pixel detectors are widely used in fundamental research, while segmented semiconductor detectors have also found applications in medicine. PantherPix, a novel 2D hybrid pixel detector designed for radiation therapy, has been shown to have adequate radiation tolerance for doses up to 3000 kGy. The study investigates the detector's radiation hardness using a Co-60 source, providing insights into its performance under different dose levels.

Summary: Radiation hardness is a key consideration in the development of particle tracking and photon imaging detector installations. The shift from DC-coupled to AC-coupled detectors in semiconductor detectors has led to better isolation of radiation-induced leakage current. Advances in detector processing technology include atomic layer deposition for high densities of capacitance and resistance, as well as flip-chip/bump-bonding interconnection technology for manufacturing pixel detector modules with high yield of noise-free and faultless pixels.

Summary: In this study, a robust clustering algorithm is proposed that can find clusters in a continuous stream of raw data in real time. This algorithm converts pixel hits measured by hybrid pixel detectors to real single-electron events. By continuously comparing with previous hits, the algorithm efficiently identifies the merging of new and old events.

Summary: This study evaluates the single event tolerance of the XRPIX x-ray silicon-on-insulator pixel sensor developed for the future x-ray astronomical satellite FORCE. Through measuring the single event upset (SEU) cross-section of the shift register on XRPIX, the saturation cross-section and threshold linear energy transfer (LET) are obtained. The estimated SEU rate in orbit is negligible due to the secondary particles induced by cosmic-ray protons.
