L-shell photoabsorption spectroscopy for solid metals: Ti, V, Cr, Fe, Ni, Cu

Description: Synchrotron radiation measurements of near-threshold and broad-range (400--1500 eV) absolute photoabsorption cross sections were made for five transition metals with {plus minus}10% overall uncertainties. Fine structure details of 2p-3d autoionizing resonances are shown with better than 1.0 eV resolution for solid metals: Ti, V, Cr, Fe, Ni, and Cu. Fine structure similar to what we measured can be produced using a multi-configuration Dirac Fock (MCDF) model if a statistical distribution is assu… more

Microwave Tokamak Experiment (MTX) ohmic heating system

Description: The ohmic heating system for the Microwave Tokamak Experiment (MTX) at Lawrence Livermore National Laboratory (LLNL) provides both the voltage for the initial breakdown phase and the energy to drive the plasma current to a value of 400 kA or greater. Providing this voltage and flux swing requires a one-turn loop voltage of about 25 volts (11 kV across the coil) and a magnetic flux swing of 2 volt- seconds. This voltage and flux swing are accomplished by charging the ohmic heating coils to 20 kA… more

Floating data acquisition system for microwave calorimeter measurements on MTX

Description: A microwave calorimeter has been designed for making 140-GHz absorption measurements on the MTX. Measurement of the intensity and spatial distribution of the FEL-generated microwave beam on the inner wall will indicate the absorption characteristics of the plasma when heated with a 140 GHz FEL pulse. The calorimeter works by monitoring changes of temperature in silicon carbide tiles located on the inner wall of the tokamak. Thermistors are used to measure the temperature of each tile. The tiles… more

In Connecticut, Moving Past Pencil and Paper

Description: A newsletter, Education Week, Editorial Project in Education, Vol. 9, No. 1. "In Connecticut, Moving Past Pencil and Paper, Teachers Evaluated On Class Behavior." Fifty-five educators were learning a new language of assessment, and the new assessments for teachers and students were pioneered in Connecticut. Connecticut introduces what is said to be the nation's most rigorous assessment of entry-level teachers. The assessment will be administered, six times a year, to new teachers. The implement… more
