The micro slit gas detector
Abstract
We describe the first tests with a new proportional gas detector. Its geometry consists of slits opened in a copper metallized kapton foil with 30 μm 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.
