A reduced basis method is introduced to deal with a stochastic problem in a numerical dosimetry application in which the field solutions are computed using an iterative solver. More precisely, the computations already performed are used to build an initial guess for the iterative solver. It is shown that this approach significantly reduces the...

The output power of backward wave oscillators and carcinotrons decrease considerably at high frequencies. This drop in power can be due to the increase in losses and manufacturing defects in their delay lines. In this study, we present measurement methods and setups developed for the characterization of delay-line performance. The developed...
