Damage to Solid-State Photodiodes by Vacuum Ultraviolet Radiation

June 1, 2005
Author(s)
Uwe Arp, Ping-Shine Shaw, R Gupta, Keith R. Lykke
We report experimental results on the stability of photodiodes obtained at three different wavelengths in the vacuum ultraviolet spectral region. Two of these experiments were based on radiation damage inflicted with excimer lasers at 193 nm and 157 nm and

40 Years of Metrology With Synchrotron Radiation at SURF

September 1, 2003
Author(s)
Uwe Arp, Steven E. Grantham, Simon G. Kaplan, Ping-Shine Shaw, Charles S. Tarrio, Robert E. Vest
the advantages of a compact synchrotron radiation source like the Synchrotron Ultraviolet Radiation Facility for metrology in the ultraviolet and extreme ultraviolet are shown. The capabilities of the different experimental stations are explained and

A SURF Beamline for Synchrotron Source-Based Absolute Radiometry

February 1, 2003
Author(s)
Ping-Shine Shaw, Uwe Arp, Howard W. Yoon, Robert D. Saunders, Albert C. Parr, Keith R. Lykke
A new source-based radiometry beamline at Synchrotron Ultraviolet Radiation Facility (SURF III) was constructed recently. The goal of this beamline is to establish a national source standard with wide spectral range from far UVto IR by using the

Characterisation of the Response of Chromium-Doped Alumina Screens in the Vacuum Ultraviolet Using Synchrotron Radiation

December 1, 2002
Author(s)
James K. McCarthy, A Baciero, B Zurro, Uwe Arp, Charles Tarrio, Thomas B. Lucatorto, A Morono, P Martin, E R. Hodgson
We have measured the response of chromium-doped alumina screens to vacuum ultraviolet radiation and derived quantum efficiency curves for the energy range from 30 to 300 eV. A model is presented to explain the structure in this curve. In addition, the
