CIRCE will enable new opportunities for scientific research and applications across a diverse array of disciplines from condensed matter physics, to medical, technological, manufacturing, space and defense industries. Imaging, spectroscopy, femtosecond dynamics, and driving novel non-linear processes are all among the potential applications.

A high peak and average power THz source is critical for driving and measuring novel non-linear phenomena with excellent signal to noise, and for studying of ultra-fast dynamical properties of materials, both of which are central to cutting edge scientific research and future high-speed electronic devices. It will also be useful for studies of molecular librations and rotations, low frequency protein motions, phonons, superconductor bandgaps, electronic and magnetic scattering and collective excitations in solids (e.g., charge density waves). The absorptive and dispersive properties of materials in the THz and sub-THz spectral range provide contrast for a unique type of imaging. The striking improvement in power CIRCE will provide could revolutionize this application by allowing full-field, real-time image capture.

These and many more potential scientific applications of CIRCE have been discussed in a number of Workshops.
