论文摘要
T2K是一项长期的基线中微子实验，自2009年以来一直在运行，为中微子振荡参数提供了一些全球领先的测量。已经提出了近检测器ND280 T2K的升级。它包括基于新读出技术的两个新的时间投影室（TPC）安装：电阻阳极微瘤（RMM）。预计该技术将减少电子通道的数量，同时维持或改善当前的ND280 TPCS的散装微羊奶性能。已经进行了一系列测试，并正在进行进一步的研究以验证这种方法。在专用的Beamtests中研究了两个RMM原型。到目前为止，所有结果仍然是初步的，这表明即使使用RMM的优势，也可以实现更好的性能，即使使用更大的垫子。
T2K is a long baseline neutrino experiment that has been operating since 2009 providing some of the world-wide leading measurements for neutrino oscillation parameters. An upgrade for the Near Detector, ND280, of T2K has been proposed. It includes the installation of two new Time Projection Chambers (TPC) based on a new read-out technology: the resistive anode MicroMegas (RMM). This technology is expected to reduce the number of electronic channels while maintaining or improving the current ND280 TPCs' bulk MicroMegas perfomance. A series of tests have been performed and further studies are ongoing to validate this approach. Two RMM prototypes were studied in dedicated beamtests. All results so far, some of them still preliminary, indicate that a better performance can be achieved, even with larger pads, thanks to the advantages of RMM.
