Design and Simulation of a Proposed Position Sensitive Nano Gas Detector

摘要

The micro GEM is a position sensitive gas electron multiplier detector with high-density and regular arrangement of holes inside a insulation foil The new idea for decreasing the applied voltage with the same electric field and also get rid of the complexity of producing regular arrangement of micro holes, is the dimension reduction of the GEM to the range of nano meter. The proposed method for producing this nano structure is anodization of the aluminium. The simulation results show that although the nano GEM has typically less gain in comparison to micro GEM, but with applied voltages in order of few Volts, high gains can be achieve by multiple nano GEM's. This novel idea which can be used for production of low voltage and portable position sensitive detectors has higher spatial resolution in comparison to commercial ones.
