Abstract

As part the phase A study for the GeoXO Lightning Mapper (LMX) Teledyne e2v has been contracted by NASA to develop and characterize an Engineering Demonstrator Unit (EDU). The full-size detector specification is under consolidation; however the format should be in the region of 1500 x 1500 pixels of about 24μm pitch. The key features and requirements are high Full Well Capacity (FWC) above 500ke- with a frame rate target above 500fps, 14 bits ADC resolution in Global Shutter mode is one of the modes considered for performance demonstration. This device must be highly sensitive at 770 nm with a QE above 80% while maintaining good MTF. This is achieved via a combination of thick silicon and reverse bias HiRho technology. The demonstrator consists of a representative reduced format of 600 x 500 of the full-size detector. This demonstrator unit has been designed, manufactured and fully characterized. In this presentation, the architecture approach to the full-size detector and the EDU will be presented along with the key silicon results from the Engineering Demonstrator Unit.
