For the last half of century scientists used electron scattering as a probe to study internal structure of nucleons and nuclei. As we gain more knowledge about the nucleon structure we start to understand that it is more complicated than originally anticipated. To pursue detailed study of basic building blocks of matter (quarks and gluons) high-current, high-duty-cycle electron accelerators in combination with large acceptance detectors were constructed. They significantly improve statistical sensitivities and highlight the full capability of electromagnetic interaction as a probe to study hadron structure. One of such facilitities is the Thomas Jefferson National Accelerator Facility that allows scientists worldwide to utilize lab's unique particle accelerator, known as the Continuous Electron Beam Accelerator Facility (CEBAF), and perform their research in CEBAF's four experimental halls. We will focus on the CEBAF Large Acceptance Spectrometer (CLAS) in Hall B and its role in exploration of the hadron structure.
