Abstract

The FAR_XITE balloon payload concept contains 10 co-aligned, hard X-ray telescopes, each containing a set of nested multilayer mirror modules and an actively shielded CZT strip detector at each focal plane. The 500 micron strip pitch provides 26 arcsecond pixels at the 4m focal length of FAR_XITE. The active shielding and advanced CZT detector techniques reduce the background at float altitudes to a few times 10-4 counts/cm2 s keV. We describe these advanced detectors and how they allow us to meet the scientific objectives of the FAR_XITE program.
