| Outline of Final Research Achievements |
FOXSI is a rocket experiment to perform high sensitivity HXR observations from 4-15 keV using the new technique of HXR focusing optics. The first FOXSI flight performed in 2012 produced the first focused image of the Sun above 5 keV: a partly occulted microflare. FOXSI ’s high dynamic range was successfully demonstrated compared to the observation of the same flare by RHESSI. In order to achieve higher sensitivity,we developed a CdTe double-sided detector with finer pitch than the FOXSI DSSD for the second flight (FOXSI-2). The strip pitch is as fine as 60 μm with a 10 μm gap between strips. 128 strips are placed on each of the top and bottom surfaces and the sensitive area is 7.67 mm × 7.67 mm.The FOXSI -2 payload was successfully launched on December 11, 2014. FOXSI -2 successfully imaged HXR emissions from multiple regions and the capability of the CdTe double-sided strip detector for solar HXR observations is successfully demonstrated.
