“…Common detectors include x-ray sensitive films and CCD cameras. These detectors have been calibrated for the soft x-ray regime, and their spectral response is used with relatively high reliability [5][6][7]. The TGS performance is determined by several TG characteristics, including TG bars material and thickness, grating period, duty cycle (spacing between bars divided by grating period), and structure accuracy.…”

A novel fabrication method for soft x-ray transmission grating and other optical elements is presented. The method uses focused-ion-beam technology to fabricate high-quality free standing grating bars on transmission electron microscopy grids. High quality transmission gratings are obtained with superb accuracy and versatility. Using these gratings and back-illuminated CCD camera, absolutely calibrated x-ray spectra can be acquired for soft x-ray source diagnostics in the 100-3000 eV spectral range. Double grating combinations of identical or different parameters are easily fabricated, allowing advanced one-shot application of transmission grating spectroscopy. These applications include spectroscopy with different spectral resolutions, bandwidths, dynamic ranges, and may serve for identification of high-order contribution, and spectral calibrations of various x-ray optical elements.

“…Les séries hydrogènoïde et héliumoïde des raies d'émission du carbone sont identifiée sur la figure. Notre résultat est très similaire à celui obtenu par Fujikawa et al [24] avec le même réseau et une source de rayonnement X produite par laser, mais présentant une durée d'impulsion piconseconde. Nous avons aussi observé les différents seuils correspondant aux éléments atomiques composant les filtres (seuil K du carbone pour le filtre de polyimide et seuil L pour le filtre de titane).…”

Résumé. Les processus dynamiques se produisant lors de transitions de phase ultra-rapide peuvent être déduits à partir de mesures de diffraction ou d'absorption de rayonnement X. Les lasers femtosecondes ont récemment été utilisés pour étudier la dynamiques de la matière au moyen d'une pompe optique et d'une sonde X : du rayonnement X K alpha produit par interaction laser plasma. Nous présentons nos plus récents résultats concernant le développement d'un sytème de spectroscopie d'absorption du rayonnement X (XAS) basée sur une source laser-plasma large bande dans la gamme 1-5 nm permettant d'atteindre une résolution temporelle femtoseconde. Le système est conçu pour sonder les dynamiques électroniques ayant lieu durant la transion de phase semiconducteur-métal du dyoxide de vanadium (VO2) lorsque celle-ci est initiée par une impulsion laser femtoseconde. Dans la présente expérience, un spectre large bande proche du seuil L du vanadium (511 eV) et du seuil K de l'oxygène (525 eV) du VO2 a été généré et mesuré avec un haut rapport signal sur bruit (100), une grande résolution spectrale ( E/E = 4.2 × 10 −3 ), et une résolution temporelle de 1,2 ps.

“…Extreme ultraviolet (EUV) spectrum plays an important role in laser-produced plasmas [1][2][3][4][5][6][7], electron beam ion trap (EBIT) [8][9][10], tokamak [11,12] and astronomy [13][14][15][16]. The EUV range contains lots of interesting spectral lines, such as the K -shell lines of carbon and oxygen, the L-shell lines of argon and aluminum, the M -shell lines of gold, and so on.…”

“…Saemann and Edimann [3], Schwanda et al [4], and Fujikawa et al [6] calibrated their spectrometers by means of a laser-generated plasma. The spectrum emitted by a laser-irradiated target was measured by the flat-field grating spectrometer (FFS) and a transmission grating spectrometer (TGS) with known efficiency simultaneously.…”

Extreme ultraviolet spectrometer for the Shenguang III laser facility

An extreme ultraviolet spectrometer has been developed for high-energy density physics experiments at the Shenguang-III (SG-III) laser facility. Alternative use of two different varied-line-spacing gratings covers a wavelength range of 10-260 Å. A newly developed x-ray framing camera with single wide strip line is designed to record time-gated spectra with ~70 ps temporal resolution and 20 lp/mm spatial resolution. The width of the strip line is up to 20 mm, enhancing the capability of the spatial resolving measurements. All components of the x-ray framing camera are roomed in an aluminum air box. The whole spectrometer is mounted on a diagnostic instrument manipulator at the SG-III laser facility for the first time. A new alignment method for the spectrometer based on the superimposition of two laser focal spots is developed. The approaches of the alignment including offline and online two steps are described. A carbon spectrum and an aluminum spectrum have been successfully recorded by the spectrometer using 2400 l/mm and 1200 l/mm gratings, respectively. The experimental spectral lines show that the spectral resolution of the spectrometer is about 0.2 Å and 1 Å for the 2400 l/mm and 1200 l/mm gratings, respectively. A theoretical calculation was carried out to estimate the maximum resolving power of the spectrometer.
