High Altitude Balloon Campaign
We plan to demonstrate the technology for advanced imaging CZT
detectors through a series of balloon-borne experiments. The first experiment, ProtoEXIST1 with
256 cm2 CZT detectors (2.5 mm pixels) was carried out on Oct 9th, 2009
in Ft. Sumner, NM. The flight last about 7 hours, and all the detector
system worked without a problem. The 2nd experiment, ProtoEXIST2
with 0.6 mmpixel CZT detectors is scheduled in Fall 2010, and the 3rd
experiement, ProtoEXIST3 with EX-ASIC in Fall 2011. These
flights will demonstrate the CZT technology needed for EXIST.
This website summarizes some aspects of the
development of ProtoEXIST as well as
provides links to EXIST and related missions.
