On Sky Observation of Delta doped CCDs Project

The objectives of this study are to adapt an existing JPL dewar and electronics for use with the STA device for observation at Palomar using an existing array (expected to have delta doped detectors produced with the MBE RTD), characterize and calibrate the performance of the array and the camera system in the laboratory (iterate), deploy to Palomar for a test run (first light check), and optimize devices and dewar configuration based on feedback.

Delta doped CCDs are unique in the combination of high QE over a wide spectral range and absolute stability. High detector sensitivity and stability are essential in achieving the science goals in mission concepts currently under development. An on-sky validation is required to earn widespread credibility and potentially for delta doped detectors to be a contender for example for PTF2 (Palomar Transient Factory). Deploying a high efficiency NUV-NIR delta doped thick CCD for on-sky observation at Palomar and demonstrating potentially new and exciting science will go a long way in establishing credibility with the astronomy community.

This is early/mid-stage (TRL 5) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
