“…10,11,12,13,14 Several groups, including a group at NASA Marshall Space Flight Center (MSFC) have already developed HXR optics with improved performance over what is currently being flown. 15,16,17 SuperHERO will take advantage of the optics being developed at MSFC, which are much better than 30 arcsec, to provide an improved view of the HXR universe.…”

SuperHERO is a new high-resolution, Long Duration Balloon-capable, hard-x-ray (20-75 keV) focusing telescope for making novel astrophysics and heliophysics observations. The SuperHERO payload, currently in its proposal phase, is being developed jointly by the Astrophysics Office at NASA Marshall Space Flight Center and the Solar Physics Laboratory and the Wallops Flight Facility at NASA Goddard Space Flight Center. SuperHERO is a follow-on payload to the High Energy Replicated Optics to Explore the Sun (HEROES) balloon-borne telescope that recently flew from Fort Sumner, NM in September of 2013, and will utilize many of the same features. Significant enhancements to the HEROES payload will be made, including the addition of optics, novel solid-state multi-pixel CdTe detectors, integration of the Wallops Arc-Second Pointer and a significantly lighter gondola suitable for Long Duration Flights.

“…Likewise, the noise level is considerably higher due to the ohmic-type contact of the detector. A Schottky-type metal contact [18] will be used in the next detector module prototype. This will provide a very low leakage current even at room temperature.…”

“…Mounted behind the WFI and operated simultaneously, the HXI will extend the energy response up to 40 keV over a field of view of 8' 8' [8]. The detectors of the HXI will consist of two layers of double-sided Si strip detectors (DSDD) and a CdTe double-sided strip detector.…”

The International X-ray Observatory (IXO) is an L class mission candidate within the science programme Cosmic Vision 2015-2025 of the European Space Agency, with a planned launch by 2020. IXO is an international cooperative project, pursued by ESA, JAXA and NASA. By allowing astrophysical observations between 100 eV and 40 keV using a very large effective collecting area mirror and state-of-the art instruments, IXO would represent the new generation X-ray observatory, following the XMM-Newton, Astro-H and Chandra heritage.The IXO mission concept is based on a single aperture telescope with an external diameter of about 3.5 m and a focal length of 20 m. The focal plane consists of a fixed and a moveable instrument platform (FIP and MIP respectively). The model payload consists of a suite of five instruments which can each be located at the telescope's focus by the MIP, these are:1. a wide field imager (WFI) based on a silicon DEPFET array; 2. a Hard-X-ray Imager (HXI), which will be integrated together with the WFI; 3. an X-ray microcalorimeter spectrometer (XMS); 4. an X-ray Polarimeter camera (X-POL) based on a gas cell with integrated anode array; 5. a High-Time Resolution Spectrometer (HTRS) based on a silicon drift detector array.In addition, the FIP will carry a grating spectrometer (XGS) mounted in a fixed position and which will allow simultaneous observations with the on-axis instrument.This paper provides a summary of the preliminary results achieved during the assessment activities presently ongoing at ESA. Whereas we will provide a brief overview on the overall spacecraft design, we will focus on the payload description, characteristics, the technology used and the accommodation on the instrument platform.
