IF Gain Bandwidth of membrane-based NbN Hot Electron Bolometers for SHAHIRA
Artikel i vetenskaplig tidskrift, 2005

SHAHIRA (Submm Heterodyne Array for HIghspeed Radio Astronomy) is a project supported by the European Space Agency (ESA) and is designed to fly on the SOFIA observatory. A quasi-optic design has been chosen for 2.5/2.7 THz and 4.7 THz, for hydroxyde radical OH, deuterated hydrogen HD and neutral atomic oxygen OI lines observations. Hot electron bolometers (HEBs) have been processed on 1 um thick SiO2 Si3N4 stress-less membranes. In this paper we analyse the intermediate frequency (IF) gain bandwidth from the theoretical point of view, and compare it to measurements.
