What are the challenges?

• Each mission concept is enabled by a diverse set of technologies• There are some overlaps, e.g., spacecraft-related

components

• But many are unique, e.g., detectors (X-ray to far-IR)

• The two largest challenges for all technologies:

•Time•Money

Delta-doped CCDs

• Atomic layer growth and doping to enhance UV quantum efficiency

• Invented in response to problems with UV response of HST CCDs• Hoenk+, APL 1992

• Used in FIREBALL balloon payload

• Baselined for LUVOIR and HabEx, …
