1. Compact X-ray and Extreme-Ultraviolet Light Sources
Uwe Arp, Lahsen Assoufid, Patrick Naulleau, Sandra Biedron , William Graves
Bringing the brightness and power of vast synchrotron and free-electron laser sources to the scale of the lab and clinic marks an important next frontier,and could transform the landscape of X-ray science and technology.
2. IR-enhanced Si reference detectors for 1-step scale transfers from 300 nm to 1000 nm
George P Eppeldauer, Thomas C Larason, Jeanne M Houston, Robert Edward Vest, Uwe Arp, Howard W Yoon
IR-enhanced Si photodiodes have improved radiometric and electronic characteristics as compared to other widely used Si photodiodes and can be used as responsivity standards in the wavelength range from 300 nm to 1000 nm. Their low predicted uncerta ...
3. Absolute pulse energy measurements of soft x-rays at the Linac Coherent Light Source
Uwe Arp, Alexander Sorokin, Ulf Jastrow, Pavle Jurani?, Svea Kreis, Mathias Richter, Yiping Feng, Dennis Nordlund, Kai Tiedtke, Philip Heimann, Bob Nagler, Hae Ja Lee, Stephanie Mack, Marco Cammarata, Oleg Krupin, Marc Messerschmidt, Michael Holmes , Michael Rowen, William Schlotter, Stefan Moeller, Joshua Turner
This paper reports novel measurements of x-ray optical radiation on an absolute scale from a
recently developed source of radiation generated in the soft x-ray regime of a free electron laser.
We give a brief description of the physics behind the ...
4. Argon mini-arc mets its match: use of a laser-driven plasma source in ultraviolet-detector
Uwe Arp, Robert Edward Vest, Jeanne M Houston, Thomas B Lucatorto
The National Institute of Standards and Technology operates two Spectral Comparator Facilities,
which are used to provide detector calibrations from the ultraviolet to the near-infrared spectral
range. One of them, the Ultraviolet Spectral Compar ...
5. First Report on Quantum Dot Coated CMOS CID Arrays for the UV and VUV
Uwe Arp, Robert Edward Vest, Zoran Ninkov, Ross Robinson, Suraj Bhaskaran
A technique has been developed for coating commercial off the shelf (COTS) detector arrays with a thin, uniform layer of quantum dots. The quantum deposition is accomplished using an Optomec Aerosol Jet rapid prototyping system. When illuminated by U ...
6. Response of large area avalanche photodiodes to low energy X-rays
Thomas R Gentile, Uwe Arp, M J Bales, R Farrell
For an experiment to study neutron radiative beta-decay, we operated large area avalanche
photodiodes (APDs) at liquid nitrogen temperature to detect X-rays with energies between 0.2 keV
and 15 keV. Whereas there are numerous reports of X-ray spect ...
7. SURF III: A flexible Synchrotron Radiation Source for Radiometry and Research
Uwe Arp, Charles W Clark, Lu Deng, Nadir S. Faradzhev, Alex P. Farrell, Mitchell L. Furst, Steven E Grantham, Edward W Hagley, Shannon Bradley Hill, Thomas B Lucatorto, Ping-Shine Shaw, Charles S Tarrio, Robert Edward Vest
The calculability of synchrotron radiation (SR) makes electron storage rings wonderful light sources for radiometry. The broadband nature of SR allows coverage of the whole spectral region from the x-ray to the far-infrared. Compact low-energy storag ...
Uwe Arp, Zhigang Li, Ping-Shine Shaw, Mathias Richter, Roman Klein, Wolfgang Paustian, Reiner Thornagel
We report on a successful bilateral inter-comparison between the Physikalisch-Technische Bundesanstalt (PTB) and the National Institute of Standards and Technology (NIST). In both laboratories deuterium lamps were calibrated using the calculability o ...
9. Bilateral NIST-PTB Comparison of Spectral Responsivity in the VUV
Uwe Arp, Ping-Shine Shaw, Zhigang Li, Alexander Gottwald, Mathias Richter
To compare the calibration capabilities for the spectral responsivity in the vacuum-ultraviolet spectral region between 135 nm and 250 nm, PTB and NIST agreed on a bilateral comparison. Calibrations of semiconductor photodiodes as transfer detectors ...
10. Long-Term Monitoring of the Ultraviolet Irradiance Scale at the Facility for Irradiance Calibration Using Synchrotrons
Zhigang Li, Ping-Shine Shaw, Uwe Arp, Charles E Gibson, Howard W Yoon, Keith R Lykke
In 2004, the National Institute of Standards and Technology (NIST) established the ultraviolet (UV) spectral irradiance scale from 200 nm to 400 nm using the calculable irradiance of the Synchrotron Ultraviolet Radiation Facility (SURF). Since the es ...
