Felch, K., et al. First tests of a 527 GHz gyrotron for dynamic nuclear polarization. in Vacuum Electronics Conference (IVEC), 2013 IEEE 14th International. 2013.
A gyrotron operating at the second cyclotron harmonic in a magnetic field of 9.7 T has produced a CW output power of 25 W at 527 GHz. The gyrotron is now being employed in Dynamic Nuclear Polarization (DNP) Applications. The gyrotron design and results of the tests are presented.
