Solar Corona At High Resolution

During the twenty years in which X-ray imaging has been used for Solar studies, every major advance in image quality has resulted in significant scientific achievements. The rapid development of grazing-incidence (GI) techniques culminated in the enormous progress resulting from the Skylab missions. Additional improvements in mirror fabrication technology since that time show that arcsecond imaging is now achievable using traditional GI systems. An alternative scheme, using normal-incidence optics offers the promise of sub-stantially improved spatial resolution and considerable cost savings. We consider what scientific objectives could be pursued if 0.1 arcsecond imaging becomes a reality in Solar coronal studies.
