I will describe an ongoing Cosmic Microwave Background experiment (ACT) designed to measure CMB anisotropies on a scale of 1 arcminute and discover clusters of galaxies through the Sunyaev-Zeldovich effect. I will discuss how to unveil the nature of dark energy, in particular how the shape of the potential of the scalar field that is driving expansion today can be reconstructed using ACT observations.
