Charge to breakout sessions
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 five science drivers for detectors astrophysics
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
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
