  • Editorial: Does atrioventricular ring motion always distinguish constriction from restriction? A Doppler myocardial imaging study
  • 2001

    • Constrictive pericarditis and restrictive cardiomyopathy can be difficult to differentiate on clinical examination. Cardiac ultrasonography is increasingly being used as the noninvasive method of choice for confirming the specific morphologic and hemodynamic abnormalities associated with either condition. Interrogation of atrioventricular valve plane motion by Doppler myocardial imaging (DMI) has been suggested as a valuable new approach that can help differentiate one from the other. We report the color DMI, pulsed DMI, and strain rate findings in 2 cases of constrictive pericarditis in which consideration of the annular motion pattern alone would not have allowed such differentiation.

  • Present status and recent results from the APS SASE FEL
  • 2002
  • Ingår i: Nuclear Instruments & Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment. - 0167-5087. ; 483:1-2, s. 40-45

    • The Low-Energy Undulator Test Line (LEUTL) at the Advanced Photon Source, Argonne National Laboratory, is intended to demonstrate the basic operation of a SASE-based free-electron laser. Goals include comparison of experimental results With theoretical predictions and scaling laws, identification of problems relevant to fourth-generation light source construction and operation and the means of addressing them, the development of operational and diagnostic techniques to optimize SASE FEL performance and increase repeatability from run to run. and performance of initial pioneering experiments capable of exploiting the unique properties of the laser. The basic layout and operational philosophy of the LEUTL experiment is presented. A summary of past results, including saturation, is reviewed, and a description of recent results is presented. We conclude with future plans, which include pressing to shorter wavelengths and incorporating user experiments into the LEUTL experimental program.

  • Dissociative recombination study of Na+(D2O) in a storage ring
  • 2004
  • Ingår i: Journal of Chemical Physics. - : AIP Publishing. - 0021-9606 .- 1089-7690. ; 121:21, s. 10483-10488
  • Tidskriftsartikel (refereegranskat)abstract
    • The dissociative recombination of Na+(D2O) ion has been studied at the heavy-ion storage ring CRYRING (Manne Siegbahn Laboratory, Stockholm University). The cross section has been measured as a function of center-of-mass energy ranging from 1 meV to 0.1 eV and found to have an E-1.37 dependence. The rate coefficient has been deduced to be (2.3+/-0.32)x10(-7)(T-e/300)(-0.95+/-0.01) cm(3) s(-1) for T-e=50-1000 K. The branching ratios have been measured at 0 eV. Of the four energetically accessible dissociation channels, three channels are found to occur although the channel that breaks the weak Na+-D2O bond is by far dominant.
