我们已经开发了一种新型微模式探测器的小型原型（5×5和10×10cm2） -一种由市上可获得的低电阻率（ρ ~ 104-108Ωcm）材料制成的微隙RPC，其位置分辨率优于50μm FWHM，并且能够以高达107Hz/cm2的计算速率工作。与传统的微图案气体探测器相比，这些探测器的主要优点是它们具有火花保护。这可能在各个领域有广泛的应用，例如医学成像。
We have developed small prototypes (5×5 and 10×10cm2) of a new type of micropattern detector—a microgap RPC made of commercially available low resistivity (ρ∼104–108Ωcm) materials having a position resolution better than 50μm FWHM and capable of operating at counting rates up to 107Hz/cm2. The main advantage of these detectors compared to traditional micropattern gaseous detectors is that they are spark protected. This may open a wide range of application in various fields, for example in medical imaging.
