Design of 132 GHz gyrotron with 3 GHz tunability for 200 MHz DNP/NMR spectrometer
A complete design of 132 GHz gyrotron for 200 MHz DNP–NMR spectroscopy application is
presented in this article. The design is performed considering a frequency tunability range of
3 GHz and output power around 100 W. A smooth frequency tunability is achieved via the
excitation of TE 03 p modes (p= 1–6) through the variation of cavity magnetic field. The start
oscillation current calculation is performed to estimate the required magnetic field for each
TE 03 p mode. Cold cavity analysis and beam–wave interaction computation are carried out …
