微缝气体探测器
The Micro Slit Gas Detector
摘要：
我们描述了一种新的比例气体检测器的第一次测试。其几何形状包括在铜金属化Kapton箔中开口的狭缝，其中30微米的阳极条悬挂在这些开口中。这样，乘法过程类似于标准MSGC。根本的区别是阳极周围没有绝缘衬底。此外，材料预算显著减少，并且消除了与充电或极化相关的问题。该探测器的老化性能正在研究中。
英文摘要：
We describe the first tests with a new proportional gas detector. Its geometry consists in slits opened in a copper metallized kapton foil with 30 micron anode strips suspended in these openings. In this way the multiplication process is similar to a standard MSGC. The fundamental difference is the absence of an insulating substrate around the anode. Also the material budget is significantly reduced, and the problems related to charging-up or polarization are removed. Ageing properties of this detector are under study.
