PandaX-III实验使用高压氙气TPC来寻找136欧姆的NLDBD。Microbulk Micromegas将用于电荷放大和读出，以便以高能量分辨率和空间分辨率记录事件的能量和轨迹。在实验的第一阶段，我们正在建造一个探测器，其中包含140公斤90%的136氚富集气体，在10巴下运行。探测器将安装在CJPL-II的干屏蔽系统中。本文介绍了PandaX-III探测器的设计，包括实验屏蔽和TPC的组成部分：高压容器、读出平面和电场笼。
The PandaX-III experiment uses a high pressure xenon gas TPC to search for the NLDBD of 136Xe. The Microbulk Micromegas will be used for charge amplification and readout in order to record both the energy and track of an event with high energy resolution and spatial resolution. In the first phase of the experiment, we are building a detector which contains 140 kg 90% 136Xe enriched gas operated at 10 bar. The detector will be installed in a dry shielding system at CJPL-II. In this paper, we wil report the design of the PandaX-III detector, including the shielding of the experiment and the components of the TPC: the high pressure vessel, the readout plane and the electric field cage.
