Spectroscopic analysis of M- and N-intrashell transitions in Co-like to Na-like Yb ions

December 19, 2021
Author(s)
Yuri Ralchenko, Dipti Goyal, Roshani Silwal, Endre Takacs, Joan Dreiling, Samuel Sanders, Amy Gall, Hemalatha Rudramadevi, John Gillaspy
The M-intrashell spectra from Co-like Yb$^43+}$ through Na-like Yb$^59+}$ ions produced in an electron beam ion trap (EBIT) at the National Institute of Standards and Technology have been studied in the extreme ultraviolet (EUV) range. A few N-intrashell

Tests of the Extended Lee Model Using Three Different Turbine Meters

June 20, 2012
Author(s)
Jodie G. Pope, John D. Wright, Sherry D. Sheckels
We report additional tests of our “extended Lee model” for calibrating turbine meters. The model accounts for 1) Reynolds number (Re) dependent drag and lift, 2) bearing static drag and 3) bearing viscous drag. Initially, we tested this model using a dual
