We write the Bloch-Kirchhoff equations for radiation damping, replacing one of the usual parameters the filling factor by the probe efficiency, i.e. the radiofrequency field strength divided the square root of power. Representative calculations are given to predict the linewidth due to damping of hyperpolarized[1-13C] Pyruvate, at a static field strength of 14.1 tesla.
