The Study report in AEgIS experiment

The AEgIS experiment aims to measuring for the first time the free fall of antihydrogen in the Earth’s gravitational field with percent order precision. In this summer student program, I was studying two topics of this experiment:​Lock-in measurement for photo-electrons from anion molecules and ​building a test set up of interferometer. Using the pure mcp background data, the signals corresponding time to the emissions of photo-electrons from anion molecules were selected. For building a test set up of interferometer,the optimization of laser couplings was done.
