Hard x-ray nanofocusing optics is important to many nano-imaging techniques at modern synchrotron facilities, including hard x-ray fluorescence nanoprobe, nano-diffraction, as well as nano-tomography. Recent developments of Multilayer Laue lenses (MLLs) [1] hold the potential to provide high-efficiency nanofocusing at sub-10 nm spatial resolution in the hard x-ray regime. Application of this type of off-axis diffractive optics requires sophisticated instrumentation with many degrees of freedom and a dedicated ultra-stable beamline, making nano-imaging experiments difficult to implement. The recent advance in bonded MLLs - a pair of off-axis MLLs bonded together to form a single 2-D focusing optic, has significantly reduced the complexity in nanofocusing instrumentation, making it possible to potentially extend high-resolution imaging to many readily available fluorescence microprobe beamlines. To optimally use such optic requires effective matching of the phase space of an x-ray source to the optic, which represents a challenge for bending magnets and wiggler beamlines. Wolter capillary optics [2] hold the potential to allow efficient focusing with micrometer-range resolution. Recent advances in the development of monolithic, axially symmetric x-ray mirror optics allow implementation of these optical elements as pre-focusing optics to potentially deliver sufficient flux-density to the MLL nanofocusing optics even on bending magnet beamlines. Furthermore, similar approach can be used to combine state-of-the-art lab-based x-ray sources with pre-focusing/MLL optics and deliver nm-scale resolution fluorescence imaging for wide-range of applications. The increased availability of hard x-ray nanofocusing optics with pre-focusing capillary will reduce the stringent requirements on beamline characteristics, thus enabling the addition of nanoscale focusing techniques to many beamlines currently using x-ray micro-beam techniques in a cost-effective and simplistic manner. Such development would greatly enhance the impact of the new and the established facilities and many existing beamlines. Grant applications that are not beyond the state-of-the-art nor do not fall within the topic will not be considered.

Grant applications are sought in the following subtopics:


a. Development of Combined Capillary and Diffractive Off-Axis 2-D Nanofocusing Optics for Hard X-ray Imaging at Nanoscale

We solicit proposals to develop a prototype system that combines a pair of bonded, high efficiency, off-axis diffractive nanofocusing optics in the energy range of 10 – 20 keV together with a single-bounce capillary pre-focusing optic to provide nanometer-scale fluorescence imaging capability at bending magnet or wiggler beamlines. The principal investigator or the proposing company must have significant prior experience in similar developments and adequate facilities for the proposed task. Applications are encouraged for those qualified proposals with already demonstrated sub-50 nm 2D spatial resolution using bonded off-axis diffractive nanofocusing optics.
