We present calculated electron stopping powers (SPs) for ten elemental solids (Al, Si, Cr, Ni, Cu, Ge, Pd, Ag, Pt, and Au). These calculations were made for electron energies between 100 eV and 30 keV, and were obtained using the same basic algorithm as

Calibrated 200 GHz Waveform Measurement

April 1, 2005

Author(s)

Dylan Williams, Paul D. Hale, Tracy S. Clement

We develop a method for mismatch-correcting temporal waveforms measured with a high-speed electro-optic sampling system. The new calibration characterizes the source in both the time and frequency domains, and accounts for all impedances and multiple
