在大亚湾反应堆中微子实验中，阻性板室(RPC)模块将被用作宇宙介子否决系统的一部分。共有189个RPC模块将覆盖实验中的三个水池。为了实现航迹重建和高效率，每个模块由4层组成，每层包含两个大小的裸室。裸室的放置在不同的层中颠倒，以减少重叠的死区。在数据分析的模拟和测试中，对模块效率和补丁效率进行了研究。已经建造和测试了143个模块。初步研究表明，4层模块和贴片中的3层效率达到了98%左右。
Resistive Plate Chamber (RPC) modules will be used as one part of the cosmic muon veto system in the Daya Bay reactor neutrino experiment. A total of 189 RPC modules will cover the three water pools in the experiment. To achieve track reconstruction and high efficiency, each module consists of 4 layers, each of which contains two sizes of bare chambers. The placement of bare chambers is reversed in different layers to reduce the overlapping dead areas. The module efficiency and patch efficiency were studied both in simulation and test of the data analysis. 143 modules have been constructed and tested. The preliminary study shows that the module and patch 3 out of 4 layers efficiency reaches about 98%.
