实验室5年无课题，他们在师范大学做出突破成果

Core Viewpoint - The research team from the University of Chinese Academy of Sciences, along with Guangxi University and Central China Normal University, has successfully observed the Migdal effect for the first time in experiments, confirming a long-standing theoretical prediction in physics [1][2][13]. Group 1: Research and Development - The Migdal effect predicts that when neutral particles collide with atomic nuclei, the recoiling nucleus transfers some energy to outer electrons, allowing them to escape the atomic binding [2][14]. - The research utilized a "micro-structured gas detector + pixel readout chip" to capture the process of single atom movement releasing electrons, effectively acting as a "camera" [2][14]. - The Topmetal pixel readout chip developed by the research team played a crucial role in detecting weak charge signals, overcoming significant challenges in high-energy physics detection [3][15]. Group 2: Technological Innovation - The Topmetal chip, measuring 2cm x 3cm, underwent extensive engineering development, requiring multiple iterations and tests over a five-year period with minimal output initially [19][20]. - The chip's design allows for direct capture of charge signals, bypassing traditional barriers posed by multiple insulating layers, thus enhancing measurement precision [3][16]. - The successful application of the Topmetal-II chip in observing the Migdal effect demonstrated its reliability and advanced capabilities in detecting extremely weak signals, highlighting China's innovation in high-end detection technology [21]. Group 3: Institutional Support and Development - The establishment of the PLAC laboratory at Central China Normal University faced initial challenges due to the lack of existing infrastructure for chip design and testing, but strong institutional support facilitated its development [22][23]. - The laboratory has evolved to include a complete technical chain for chip design, packaging, and testing, and has begun to train undergraduate and graduate students in integrated circuit technology [22][23]. - The supportive environment at the university allowed the research team to persist through initial low-output years, ultimately leading to significant breakthroughs in their research [23].
