  2. Charge to Breakout Sessions Breakout groups will determine: the most pressing questions in their area that leverage QLIDs the most important detector characteristics for answering these questions the specific technologies that are most promising for achieving these characteristics the hurdles for implementing these technologies the R&D roadmap for overcoming these hurdles the funding opportunities for executing the R&D roadmap The four areas are: biomedical astrophysics Earth system science defense/homeland security Group leads will present findings in the final session of the workshop. 3

  4. The Top Five Science Drivers for Detectors: Astrophysics What is dark energy? What is dark matter? Do Earth-like planets exist? Does extraterrestrial life exist? Evolution of galaxies & the universe: what was our past and what will be our future? 5

  5. The Top Detector Characteristics for: Astrophysics zero read noise in-pixel wavelength discrimination 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 capabilites, yet retain low noise ??? 6

  6. Reference Chart: Key Detector Characteristics Homeland Safety Biomedical Imaging Earth System Science Defense Quantum-Limited Imaging Detector Read Noise Dark Current QE λ λ/Δλ Δt P

  7. Detector Performance Requirements for: Astrophysics 8

  8. The Most Promising Detector Technologies for: Astrophysics GM-APD: zero read noise SPNW: zero read noise, wavelength, etc. TES STJ MCP ??? ??? 9

  9. Hurdles for the Most Promising Detector Technologies for: Astrophysics GM-APD: afterpulsing, …. SPNW: cold operation, …. TES: extremely cold, not ideal wavelength coverage STJ: same as TES ??? ??? ??? 10

  10. Detector R&D Roadmap for: Astrophysics GM-APD demonstrate ~64x64 diode/ROIC array at 150 K design megapixel array and demonstrate at telescope ???? SPNW Materials demonstrate low dark curent mid-wave MCT ??? ??? ??? ??? 11

  11. Funding Possibilities: Astrophysics NASA ROSES APRA NSF ATI DARPA MTO BAA ??? ??? 12
