[24.02] Prospects for Hard X-ray Imaging with Focusing Optics

M. Pivovaroff (UC Berkeley, Space Sciences Laboratory)

Currently, hard X-ray imaging of the sun relies on rotation modulation collimators (RMCs). While RMCs can provide arc-second quality images, as vividly demonstrated with RHESSI, they presently offer limited dynamic range and modest effective area. One path around these limitations is the use of grazing incidence optics. Previously restricted to energies below ~10 keV, recent advances in multilayer and substrate development now make it possible to build wide-field, hard X-ray imaging optics with several arc second spatial resolution that operate up to 100 keV.

In the first part of this talk, we discuss the basic principles and underlying technology that have made these advances possible. We also present results from groups currently building hard X-ray optics to demonstrate the feasibility of this approach. In the second part of the talk, we discuss hard X-ray telescope designs for studies of microflares and normal flares that will complement upcoming soft X-ray imaging missions (e.g., Solar-B and RAM).
