  1. 1. Microfabrication of miniature x-ray source and x-ray refractive lens

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Carolina Ribbing; Robert Baptist; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; microfabrication; diamond; field emission; Teknisk fysik; TECHNOLOGY Engineering physics; TEKNIKVETENSKAP Teknisk fysik; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Abstract : In several x-ray related areas there is a need for high-precision elements for x-ray generation and focusing. An elegant way of realizing x-ray related elements with high precision and low surface roughness is by the use of microfabrication; a combination of semiconductor processing techniques and miniaturization.

  2. 2. Mid- and near-infrared NICE-OHMS techniques for ultra-sensitive detection of molecules in gas phase

    University dissertation from Umeå : Umeå universitet

    Author : Thomas Hausmaninger; Ove Axner; Kyle Crabtree; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spectrometry; NICE-OHMS; trace gas detection; acetylene; methane; isotopologues; near-infrared; mid-infrared; shot-noise; optical parametric oscillator; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Abstract : Noise-immune cavity-enhanced optical heterodyne molecular spectrometry (NICE-OHMS) is a technique for ultra-sensitive detection of molecular absorption and dispersion. For highest performance, the technique combines cavity enhancement (CE) with frequency modulation (FM); while the former increases the effective interaction length between the light and the analyte by several orders of magnitudes, the latter removes the in-coupling of 1/f noise and makes the signals background free.
