MgB2 hot electron bolometer mixers (HEBs)
Project
While the most sensitive detectors for space THz heterodyne detection are hot electron bolometers (HEB) based on NbN superconducting material they are limited in bandwidth (~ 4 GHz). We are developing such mixers using the new superconductor MgB2, which opens possibilities to increase the bandwidth to more than 10 GHz. Wider bandwidth is essential for future missions, which aim to look deeper in space, where the objects move faster and the arriving signals undergo more redshifts.
Objective
Development of MgB2 HEB mixers to provide higher bandwidth and extend the observation capability of THz heterodyne receivers to the deeper space with higher dynamics.
Impact
Paving the path for future THz space missions, which aim to study and observer the highly dynamic regions in deeper space, where wide bandwidth detectors are highly demanded.
