Modern Dynamic Nuclear Polarization (DNP) experiments often utilize gyrotron sources for irradiation of electron spins at 140-593 GHz. The total cost of ownership, size, and complexity of gyrotrons, however, limits wider adoption. The introduction of lower-cost and more compact sources can have a significant impact on the DNP community. This contribution describes the development of a 263 GHz EIK, design of transmission line for optimal irradiation of the DNP NMR sample, and detailed performance characterization for DNP experiments.
