Figure 2. CASIMIR’s completed 1.2 THz flight mixer. The device uses SiS junctions to cover the 1.1-1.25 THz frequency (270-240 µm) range with an IF Bandwidth of 4-8 GHz.
Figure 3. Point-spread functions measured with the HAWC 12x32 bolometer array. Detector noise is close to the background-limit on SOFIA, and >90% of the detectors are operational.
