We propose a novel scenario for the detection of radio signals from the decay of axions and axion-like particles, termed *axion gegenschein*. Ambient radiation arriving from astrophysical radio-bright objects stimulate the decay of halo dark matter in Milky Way creating a *countersource* emitting photons at frequencies half the axion mass and exhibiting the spatial dimensions and features of...

Emerging high power THz sources show great promise for electron acceleration and manipulation within mm-scale waveguides. For efficient and phase synchronous interaction a thorough characterization of these waveguides is required for which a technique has been developed and tested.
