2020年10月，中国地质大学数理学院刘丰铭教授及其合作者在物理学期刊《PHYSICAL REVIEW LETTERS》（PRL）上发表了题为“Metafluids beyond the Bulk Modulus”的研究论文，第一作者为刘丰铭教授。
探测无中微子双贝塔衰变的PandaX-Ⅲ实验需要一个能同时对多个Micromegas探测器的增益、能量分辨、坏道分布、位置分辨等性能参数进行测试的平台，为此中国原子能科学研究院建立了PandaX-Ⅲ实验探测器测试平台。本文采用由光蚀刻技术制作的Bulk Micromegas对该测试平台进行研究：利用55Fe放射源在Ar+10%CO2的流气情况下，使用基于AGET读出芯片制作的通用读出电子学进行数据...
利用光蚀刻技术制作的有效面积为10 cm×10 cm的多通道Bulk Micromegas探测器。对探测器的各通道进行了电容测试，显示探测器在Ar + 10％CO 2气体中，使用55 Fe放射源和自主开发的基于APV25前端卡的数字化电子学，对制作的有效面积为10 cm×10 cm的探测器进行。该探测器现有全部工艺国产化，并能进行批量生产，成品率接近100％。了测试，其结果显示探测器性能良好，能得...
