Preliminary Experimental Results for Impulse Amplification in a Wideband Traveling Wave Tube
We report on our ongoing work on impulse amplification using a custom, wideband helix traveling wave tube (TWT) amplifier. We have specifically conducted experiments and simulations of large signal amplifications of bipolar differentiated-Gaussian impulses. Our results confirm that the saturated peak power for an impulse surpasses the saturated power obtained with CW sinusoidal signals, aligning with earlier observations. In particular, we experimentally observed ~1.4 kW of instantaneous peak power with a large differentiated-Gaussian impulse, despite a saturated power limit for CW sinusoidal excitation of ~150W.
