The Top Five Science Drivers for Detectors: Astrophysics What is dark energy? (QE, read noise, DC) What is dark matter? (QE, read noise, DC) What processes alter the surfaces of planets/moons? (thermal imaging, LIDAR, dynamic features with DFPA) Do Earth-like planets exist? Does extraterrestrial life exist? (O3, MIR) When was the Universe enriched with metals? How were galaxies assembled? 5
The Top Detector Characteristics for: Astrophysics in-pixel wavelength discrimination high QE across broad range low dark current zero read noise time-tagging (for LIDAR) larger formats (>10K x 10K) lower power, higher temp. operation lower cost operation (e.g. standardized ASIC, easier than SIDECAR) high dynamic range: 1 - 1E7 photons high speed capabilities, yet retain low noise 6
