Development of ultra-low noise TESs for far-infrared applications
The far-infrared (FIR) foreground level in space is extremely low, necessitating highly sensitive detectors for space-based continuum observations. To achieve photon-noise-limited performance, FIR detectors require a noise equivalent power (NEP) lower than 3×10 -19 W/Hz 1/2 and a per-pixel saturation power (P sat ) r...
