Real-time antiproton annihilation vertexing with submicrometer resolution
Original language description
Primary goal of the AEgIS experiment is to precisely measure the free fall of antihydrogen within Earth's gravitational field. To this end, cold (approximate to 50 K) antihydrogen will traverse a two-grid moir & eacute; deflectometer before annihilating onto a position-sensitive detector, which shall determine the vertical position of the annihilation vertex relative to the grids with micrometric accuracy. Here, we introduce a vertexing detector based on a modified mobile camera sensor and experimentally demonstrate that it can measure the position of antiproton annihilations within 0.62-0.22+0.40 mu m, a 35-fold improvement over the previous state of the art for real-time antiproton vertexing. These methods are directly applicable to antihydrogen. Moreover, the sensitivity to light of the sensor enables in situ calibration of the moir & eacute; deflectometer, substantially reducing systematic errors. This sensor emerges as a breakthrough technology toward the AEgIS scientific goals and will constitute the basis for the development of a large-area detector for conducting antihydrogen gravity measurements.
