As photodetectors rapidly develop towards high speed and huge scale, the signal frequency of digital circuits reaches hundreds of MHz or even GHz. As the operating frequency continues to increase, traditional microstrip lines cannot be simply regarded as metal lines and are prone to signal integrity problems. This paper uses HFSS (High Frequency Simulator Structure) software to establish a high-speed microstrip line crosstalk simulation analysis model. Based on this model, the crosstalk problem of discontinuous microstrip lines under high-frequency conditions is studied, and its near-end crosstalk (S31) and far-end crosstalk (S41) are obtained. The influence of signal frequency, microstrip line thickness, microstrip line width, and microstrip line spacing on the crosstalk intensity is analyzed. The results show that the crosstalk intensity of discontinuous microstrip lines increases first and then tends to be flat with th 1e change of signal frequency; the near-end crosstalk S31 shows an increasing trend with the increase of microstrip line thickness; the near-end crosstalk S31increases with the increase of microstrip line width; the crosstalk intensity decreases with the increase of microstrip line spacing.

The cross strip (XS) anode detector is a photon counting imaging detector with high spatial resolution and good position resolution. This kind of detector is widely used in material science, medical imaging and environmental monitoring, especially in detecting weak photon signals. However, in order to fully tap the potential of the XS anode detector, advanced algorithms are needed to optimize the processing of image data. Centroiding algorithm, as one of the key factors affecting the imaging of detector, plays a vital role in improving the performance of detector. The traditional centroiding algorithm mainly relies on the peak value of charge distribution to locate the centroid, but it is easily disturbed by noise. In order to weaken the negative effect of noise, this paper designs a centroiding algorithm based on convolution, which selects data by setting threshold value and calculates the average value of all data larger than threshold value. In addition, considering that the input signal may introduce noise, the filtering operation is specially introduced. The experimental results demonstrate the superiority of the proposed method in calculating the centroid position. Compared with the traditional algorithm, the mean value interpolation convolution algorithm proposed in this paper improves the precision of solving the centroid coordinates and has good robustness. Specifically, the error range of the algorithm is obviously smaller than that of the traditional algorithm, and its error range is no more than 5%. This means that higher spatial resolution and faster counting rates can be expected without sacrificing too much accuracy.

Jinyao Duan, Jinkun Zheng, Yang Yang, Yuchao Song, Anpeng Lai, Bo Wang, Weiwei Cao, Yonglin Bai

Proceedings Volume 12959, 129590Z (2023) https://doi.org/10.1117/12.3007806

KEYWORDS: Diffusion, Anodes, Photodetectors, High speed photonics, Electron transport

In this paper, we mainly study the problem of electron cloud diffusion in high-speed ultraviolet photonic imaging detectors. In this paper, the size of the electron cloud transmitted by the microchannel plate and the anode in the high-speed ultraviolet photon imaging detector is studied by simulation, including the bias angle, pore diameter, voltage (U) and distance between MCP and anode (l) on the electron cloud received by the anode. the diffusion radius of the electron cloud increases with the increase of the bias angle, and the voltage (U) and the distance (l) between the MCP and the anode on the electron cloud received by the anode. The research shows that the diffusion radius of the electron cloud increases with the increase of the bias angle, the diffusion radius of the electron cloud. When U is larger, the energy of electron cloud is also higher. When the voltage increases to 1900V, the electron movement speed increases linearly with the increase of U. Moreover, the diffusion distance of the electron cloud radius increases with the increase of the transmission distance l. When the distance is 2 mm, a maximum electron diffusion radius is obtained. When the bias angle is 10°, the pore diameter is 10um, the voltage is 2000V, and the distance l is 0.5mm, the diffusion ratio of the electron cloud is 5.5.
