Summary: This paper introduces a method for performance testing of automotive LiDAR sensors that can be used in dynamic test scenarios. A spatio-temporal point segmentation algorithm is proposed to separate the LiDAR signal of moving reference targets. An automotive-graded LiDAR sensor is evaluated in four harsh environmental simulations based on real road fleet data in the USA, and four vehicle-level tests with dynamic test cases are conducted. The results show that the performance of LiDAR sensors may be degraded due to environmental factors such as sunlight, object reflectivity, cover contamination, etc.

Summary: Silicon photomultipliers (SiPMs) are highly-sensitive photodetectors, and there has been increasing interest in assessing their performance deterioration under high radiation fluences. This study irradiated different FBK SiPM technologies with protons and found that the primary noise of the detectors significantly worsened with increasing fluence. However, other performance parameters remained relatively stable. The study also introduced new methodologies for estimating breakdown voltage and characterizing SiPM performance under high noise levels. Additionally, the spatial localization of proton-induced defects in the devices was analyzed using emission microscopy (EMMI) technique.

Summary: This article presents the characterization of the spacial and timing resolution of the novel TI-LGAD technology. The TI-LGAD technology aims to achieve 4D pixels with accurate position resolution and precise timing determination for MIPs. By separating the pixelated LGAD pads with physical trenches, this technology reduces the interpixel dead area and mitigates the fill factor problem. The TI-RD50 production studied in this work is the first of pixelated TI-LGADs. The characterization was conducted using a scanning TCT setup with an infrared laser and a Sr-90 source setup.

Summary: In this study, various types of SiPM structures produced in FBK (Trento, Italy) were irradiated with 40 keV X-rays at different doses up to 100 kGy in silicon. Online measurements were conducted after each irradiation step, followed by offline functional characterization after one month of room temperature annealing. The study focused on the effects of irradiation on the reverse current-voltage curves, dark count rate, correlated noise probabilities, and photon detection efficiency of the SiPMs. By comparing the measurement results and considering the internal structure and fabrication processes, different deterioration mechanisms were identified, supported by TCAD simulations on the effects of ionizing radiation inside the microcells.

Summary: Chipless radio-frequency identification (RFID) sensors are not widely used due to their limited sensitivity compared to mature sensing technologies. However, there is little research on the relationship between the performance of chipless or microwave sensors and the materials used to fabricate them. In this study, we simulate the impact of substrate materials on the performance of a chipless RFID sensor for humidity detection. The dielectric parameters of the substrate material play a crucial role in maximizing sensor performance, especially in relation to the desired application and the effective dielectric properties of the sensitive material used.

The study found substantial temporary damage during low-temperature irradiation, regardless of oxygen concentration and wrapping material. The wrapping material had an impact on the relative light loss, with the 3M(TM) Enhanced Specular Reflector Film showing the largest loss. The light loss was less at warmer temperatures and similar to that in standard atmosphere with 3% oxygen concentration. Evidence of a plateau in the radical density was seen for the data at 0 degrees C.
