For more than 25 years, the Physikalisch‐Technische Bundesanstalt has been strongly
engaged in the field of metrology using synchrotron radiation. In Berlin, this research …

Covering state-of-the-art advances, novel applications, and future perspectives, this volume
presents new directions on the basic studies of charged particle and photon interactions with …

A four-crystal monochromator beamline has been installed by the Physikalisch-Technische
Bundesanstalt at a bending magnet of the electron storage ring BESSY II. The …

The photon energy dependence of the mean energy W required to produce an electron-hole
pair in silicon for photons with energies between 50 and 1500 eV was determined from the …

The metrological fields of photometry and radiometry and their associated units are closely
linked through the current definition of the base unit of luminous intensity—the candela …

Ionizing radiation can be detected by the measurement of the charge carriers produced in a
detector. The improved semiconductor technology now allows detectors operating near the …

During the past decade, high-accuracy soft x-ray radiometry has increasingly gained in
importance. In particular, its routine availability is a prerequisite for the development of …

At the BESSY II storage ring, the Physikalisch–Technische Bundesanstalt (PTB) will operate
insertion devices dedicated to radiometric use. One branch of the appendant beamline …

This paper represents a call to the broader XAS community to more closely assess dose, as
well as the other experimental factors (detection method, temperature, pressure and sample …

Ratios of total cross sections for electron-impact ionization and photoionization in Ar, Kr, and
Xe in the energy range from 140 to 4000 eV for electrons and from 16 to 1012 eV for …
