The High resolution Coronal Imager Project

Listed in NASA Data Portal

Description

The telescope design is a direct continuation of the development from NIXT to TRACE and AIA: we propose a Ritchey-Chr´etien with plate scale sufficient to provide 0.1 arcsec pixel size, and multilayer coatings on two D-shaped halves, so that there are two wavelength channels available. The detector is a large-format back-illuminated CCD, providing high quan tum efficiency and rapid readout for high im age cadence.

Channel selection is made via selectable focal plane filters. An H-telescope with NTSC (TV) output is included for real-time pointing verification during the flight. Major components of this new payload have been developed and qualified for the Hinode XRT instrument, SDO program (AIA & HMI) and for the Solar Ultraviolet Magnetograph Investigation (SUMI) sounding rocket.

This has helped keep the development costs for Hi-C sig nificantly lower than they otherwise would have been. The vehicle layout includes all major components needed for the flight demonstration. .

It has a to total length of 108.9 inches and a launch weight of 562.9 pounds. The vehicle is the standard NASA 22-inch diameter shell. The proposed experiment design is based on the SAO NIXT and TXI instrument designs.

A detailed weight breakdown is provided in Figure 5. As evidenced by Table 1, every component in the proposed mission has heritage in multiple successful instruments. Now we propose to ex tend the telescope magnification to the diffrac tion limit.

AIA chose to extend the TRACE resolution to a full-sun field of view and now we are proposing to extend TRACE by increasing the magnification on the secondary mirror. The technologies required to build AIA are identical to that for Hi-C and every major contribution to the development of Hi-C is performed by the teams that built AIA (SAO, LMSAL)
