提出了一种用于未来圆对撞机时间投影室的混合结构离子回流抑制气体探测器组件的新概念。它是一个混合结构级联气体电子倍增器（GEM）与Micromegas检测器。Micromegas和GEM都有能力自然减少放大区产生的大部分离子。GEM还充当前置放大器设备，并与Micromegas一起增加气体增益。混合探测器的可行性测试使用${}^{55}$ Fe X射线源进行。对于5.9keV的X射线，能量分辨率优于27%。结果表明，在增益为5000的混合读出结构中，回流比可以达到优于0.2%。
英文摘要：
A new concept for a hybrid structure gaseous detector module with ion backflow suppression for the time projection chamber in a future circular collider is presented. It is a hybrid structure cascaded Gas Electron Multiplier (GEM) with a Micromegas detector. Both Micromegas and GEM have the capability to naturally reduce most of the ions produced in the amplification region. The GEM also acts as the preamplifer device and increases gas gain together with the Micromegas. Feasibility tests of the hybrid detector are performed using an ${}^{55}$Fe X-ray source. The energy resolution is better than 27% for 5.9 keV X-rays. It is demonstrated that a backflow ratio better than 0.2% can be reached in the hybrid readout structure at a gain of 5000.
