Improved system and method of X-ray laser microscopy that combines information obtained from both X-ray diffraction and X-ray imaging methods. The sample is placed in an ultra-cold, ultra-low pressure vacuum chamber, and exposed to brief bursts of coherent X-ray illumination further concentrated using X-ray mirrors and pinhole collimation methods. Higher resolution data from a sample is obtained using hard X-ray lasers, such as free electron X-ray lasers, and X-ray diffraction methods. Lower resolution data from the same sample can be obtained using any of hard or soft X-ray laser sources, and X-ray imaging methods employing nanoscale etched zone plate technology. In some embodiments both diffraction and imaging data can be obtained simultaneously. Data from both sources are combined to create a more complete representation of the sample. Methods to further improve performance, such as concave or curved detectors, improved temperature control, and alternative X-ray optics are also disclosed.

X-ray laser microscopy system and method

An apparatus and process for frost control for the ambient air heat exchanger of a space conditioning apparatus. The ambient air heat exchanger is immersed in a fluidized bed enhancing the heat transfer and physically reducing frost formation. In a preferred embodiment, the fluidized bed is supported by a support bed of non-fluidized solid particles. In one of the embodiments the particulate beds may be desiccant materials. The space conditioning apparatus and method of frost control of this invention permits smaller ambient air heat exchangers and accommodates greater transient conditions due to the enhanced heat transfer and physical prevention of ice formation resulting from the fluidized bed.
