چکیده

A metre-length flexible hollow glass fibre with 20 µm-bore and 1.5 mm-cladding diameters for transporting a synchrotron X-ray beam and controlling the trajectory has been examined. The large cladding diameter maintains a moderate curvature to satisfy the shallow glancing angle of total reflection. The observed transmission efficiency was more than 20% at 12.4 keV. As a demonstration, a wide-area scan of a synchrotron radiation beam was performed to identify the elements for a fixed metal film through its absorption spectra.

Generation of Coherent, Broadband X-Ray and Mid-IR Pulses in a Noble-Gas-Filled Hollow Waveguide

We discuss a proposed experiment on guiding of a high-repetition rate, 20 GW, CO2 laser beam in a gas-filled hollow glass waveguide. Extended interaction of the 3ps pulses with a gas Kerr medium will be used for measurements of nonlinearity at 10 um, and supercontinuum generation followed by pulse compression. Feasibility of 3-5 keV X-ray production via HHG is presented.

Monocapillary Optics Developments and Applications

Hollow glass tubes are in use at Cornell High Energy Synchrotron Source (CHESS) as X-ray optics in the 4 to 25 keV range to take large diameter, fairly parallel X-ray beams and compress them into smaller diameter, more divergent beams for various kinds of X-ray applications. The optics come in two forms: 1) multibounce condensing capillaries for making submicron diameter beams and 2) one-bounce...

Evaluating the Sintering Temperature Control Towards the Adsorptivity of Ammonia onto the Natural Zeolite Based Hollow Fibre Ceramic Membrane

The disproportionate quantity of ammonia presence in water has led to serious drinkable water scarcity worldwide. The abundant source of mineral and superior cations selectivity has made natural zeolite as a good adsorbent for the ammonia removal. This work aims to fabricate natural zeolite based hollow fibre ceramic membrane (HFCM) via extrusion based phase inversion and sintering techniques f...
