Abstract

Microwave sample irradiation is essential to perform DNP. Waveguides provide an effective way of coupling the output of a microwave source to the electron spins. Indivertibly, the waveguide introduces a significant thermal heat load into the sample space of our dDNP probe. The use of a circular stainless steel waveguide with an internally electroplated layer of copper offers an effective, economical solution to address this problem.
