3IT Collaboratory 2009 Research Symposium

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.

The Top Detector Characteristics for: Astrophysics1. zero read noise2. in-pixel wavelength discrimination3. larger formats (>10K x 10K)4. lower power, higher temp. operation5. Lower cost operation (e.g. standardized

ASIC, easier than SIDECAR)6. high dynamic range: 1 - 1E7 photons7. high speed capabilites, yet retain low noise8. ???
