Reliability testing for Single Event Effects (SEEs) requires accurate localization of heavy-ion tracks from projection images. Conventional localization often relies on handcrafted features and geometric fitting, which is sensitive to noise and difficult to accelerate in hardware. This paper presents a lightweight detector based on YOLOv5n that treats charge tracks in Topmetal pixel sensor projections as distinct objects and directly regresses the track angle and intercept, along with bounding boxes, in a single forward pass. On a synthetic dataset, the model achieves a precision of 0.9626 and a recall of 0.9493, with line-parameter errors of 0.3930° in angle and 0.4842 pixels in intercept. On experimental krypton beam data, the detector reaches a precision of 0.92 and a recall of 0.96, with a position resolution of 52.05 μm. We further deploy the model on an Xilinx Alveo U200, achieving an average per-frame accelerator latency of 3.1 ms while preserving measurement quality. This approach enables accurate, online track localization for SEE monitoring on Field-Programmable Gate Array (FPGA) platforms.

The Multi-Purpose Detector (MPD) at the Nuclotron-based Ion Collider fAcility (NICA) is designed to acquire precise energy and timing information of charged hadrons, electrons, and photons produced during heavy ion collisions. The inner tracker system plays an important role on the MPD and is positioned closest to the collision vertex to provide high-resolution position measurements of charged particles. Monolithic Active Pixel Sensors (MAPS) are employed in the ITS. A key challenge in MAPS design is managing this high data throughput while adhering to strict material budget constraints. A high speed data transmission link composed of a Phase Locked Loop (PLL) and a serializer is employed in the MAPS. The PLL generates a 550 MHz clock for the serializer. The serializer converts 10-bit 110 MHz parallel data into a 1.1 Gbps serial data. A test chip integrating both the PLL and serializer has been designed and manufactured in a TSMC 180 nm process. Test results show that the PLL can generate a stable 550 MHz clock signal and the serializer outputs a steady 1.1 Gbps serial data. The height of the eye diagram and the total jitter of the high-speed serial data is about 112 mV and 598 ps, respectively, with a duty-cycle distortion of 29.3 ps.
