W.P. HEB-Mixer film fabrication and optimization

This work package concerns the development of phonon-cooled Hot Electron Bolometers (HEB) Mixers for observations above 1 THz (SOFIA) with the goal of fundamental study and optimization of ultrathin NbN film parameters.

The heterodyne detection of weak THz signals in radioastronomy with ultrathin superconducting microbridge bolometers necessitates optimized NbN film qualities to allow mixing with IF bandwidths up to 10 GHz. In this first step the following activities has been started:
