Fresnel zone plates for Achromatic ImagingSurvey of X-ray sources

摘要

A telescope with Fresnel Zone Plates has been contemplated to be an excellent imaging mask inX-rays and gamma-rays for quite some time. With a proper choice of zone plate material, spacingand an appropriate readout system it is possible to achieve any theoretical angular resolution. Weprovide the results of numerical simulations of how a large number of X-ray sources could beimaged at a high resolution. We believe that such an imager would be an excellent tool for a futuresurvey mission for X-ray and gamma-ray sources which we propose.
