Micro-xrf Instrument Developed in Combination with Atomic Force Microscope
A new micro-XRF instrument was developed in combination with an atomic force microscope (AFM). A small pinhole of 5 or 10 μm was made on the AFM cantilever. The center of the micro X-ray beam generated by a polycapillary X-ray lens was passed through the pinhole. The present experiment demonstrated that the size of the original X-ray beam of 48 μm produced by the polycapillary lens was reduced ...
متن کاملMicro XRF Imaging of Daguerreotypes
century. The process involved polishing a silver coated copper plate, made photo sensitive by exposure to halogens, then exposed to light, and finally coated with gold. This complex, intricate process has yielded some of the most iconic images of the 19 th century. Unfortunately, in some instances plate interaction with storage materials have yielded objects ranging from pristine to disfigured....
متن کاملTechnology Developments towards a Combined Xrd-xrf Instrument for Planetary Surface Analysis
Geochemical analysis of the surface material of terrestrial type planets is of fundamental importance in understanding the geological context of the planetary environment. Consequently this analysis should be performed whenever possible and indeed this has occurred on a number of previous landers. Current techniques include X-ray fluorescence (XRF) and Rutherford back-scattering of alpha partic...
متن کاملSpatially and temporally resolved optical measurements in micro discharges
Optical measurements provide a convenient way to determine plasma properties such as particle densities and temperatures. Since optical measurements are usually conducted externally, they give only little information about the spatial distribution of the plasma. This is especially egregious when dealing with micro discharges. Firstly, micro discharges usually show a spatial non-uniformity, and ...
متن کاملA New Neurosurgical Instrument : A Micro - Vibrato -
O B J E C T I V E : We developed an instrument (a dissector tool with micro vibrating system) to make make brain tissue dissection easy and safe. Method: We used this instrument and conventional technique to dissect 18 fresh cadaver sheep brains (9 of them were dissected by the vibrating-dissection technique and the remaining 9 with a conventional dissector). Dissection and separation were grad...
