Abstract :
The behaviour of a gyrotron oscillator designed for DNP-NMR spectroscopy within the non-stationary operating regime is investigated in detail and compared to numerical simulations. The response of the device to the control parameters is explored and a variety of non-stationary regimes are categorized. The main features observed in the experiment could be reproduced in the simulation, including the observed behavior in the chaotic regime.
