The DArk Matter Particle Explorer (DAMPE) is a space-based mission designed as a high energy particle detector for measuring cosmic-rays and gamma-rays in space. It was successfully launched on December 17, 2015, and since then it has been in stable data taking for more than one year. The large geometric factorand thick calorimeter enables DAMPE to have very good potential to measure cosmic-rays from 20 GeV up to 100 TeV. Here we analyze the proton component using the DAMPE flight data. Comprehensive Monte-Carlo simulations have been employed to validate the event selections and estimate the efficiency as well as the geometry factor. The analysis progress is reported and discussed
