We present the application of a short rise (∼150 ns) 250 kA linear transformer driver (LTD) to wire array z-pinch loads for the first time. The generator is a modification of a previous driver in which a new conical power feed provides a low induct

Improvements in synchrotron radiation and high-temperature black-body sources will provide a method of realizing scales of spectral radiance and irradiance with uncertainties comparable with those provided by absolute cryogenic radiometers. This pape

A comparison has been made between a calibrated thermopile and an argon ionization chamber as absolute detectors of radiant flux of wavelengths 584 A and 735 A. Corrections were applied to the data in order to account for the absorption due to gases

Electron synchrotrons are becoming increasingly important as sources of extreme uv radiation for physical experiments. The NBS 180-MeV machine has been utilized for gas absorption studies over a four-year period, during which a 3-m grazing incidence

A new monochromator system has been developed that permits the in situ calibration of its optical components and allows the calibration of a photodiode against a calculable synchrotron radiation source in the spectral range extending from 116 to 254
