Grazing incidence optics
Grazing Incidence Optics

HEROES hard X-ray optics are full-shell electroformed-nickel-replicated (ENR) mirrors coated with iridium to enhance high-energy reflectivity.

They areconical approximations to Wolter Type 1 geometry, with a monolithic shell structure containing both “parabolic” and “hyperbolic” segments.

* Developed in-house at MSFC

HEROES Astrophysics Analysis - Crab

  • The Crab Nebula was observed for 3 hours

  • It was detected about 4’ off-axis

  • Spectrum is consistent with expected values

  • Star camera misalignment with rising elevation found in post-flight testing

SuperHERO – LDB Payload (See Poster)

  • LDB flights can last more than three weeks, offering improved sensitivity over the HEROES payload. However, a complete redesign of the payload is necessary.

  • Mass Minimization

  • Power (Solar Panels)

  • Thermal Analyses

  • Flight Profiles

  • These detectors allow for improved spatial resolution, response and background rejection when coupled with active shielding.

  • RAL’s detectors will provide a complete telescope suitable for Explorer mission opportunities.

  • Cooling schemes have been explored for optimal performance (and also to minimize power)
