The Gemini MCAO system, GeMS, has been in integration and test in the lab for over a year. We present the main highlights of the integration and tests of the system. Issues we encountered, how we solved it. We will focus on the following points:
Registration
WFS subaperture (quadcell) centroid gains
tomographic NCPA
synthetic matrices and why we use it
dependance over zenith angle
flexures calibrations
extrapolator issues
temporal performance
