G Sun, Rui-Hua Xie, M C. Niklaus
… structures of the N-substituted fullerenes, C 33 N 9 and C 44 N 6 , to have C 3 symmetry. While some level of symmetry … this explicitly for two particular cases, C 40 and C 44 N 6 , for which the authors of Ref. [1] only considered …

Enabling accurate differential calibration of modern GPS receivers

November 26, 2012
Author(s)
Stefania Romisch, Victor S. Zhang, Thomas E. Parker, Steven R. Jefferts
The difference between the local time reference and a GNSS receiver's internal time base is an essential contributor to the calibration of that receiver when used as a timing device. In the past, in the absence of a PPS output signal provided by the

In Search of a New Primary GPS Receiver for NIST

November 26, 2012
Author(s)
Marc A. Weiss
A previous publication showed problems with the current NIST Time and Frequency Division primary GPS receiver [1] when used for Precise Point Positioning (PPP)-based carrier phase time transfer. We confirm that, for this receiver, boundary discontinuities

The MINOS experiment uses a beam of predominantly muon-type neutrinos generated using protons from the Main Injector at Fermilab in Batavia, IL and travelling 735 km through the Earth to a disused iron mine in Soudan, MN. The 10 us-long beam pulse contains

Synchronization between remote sites for the MINOS experiment

November 26, 2012
Author(s)
Stefania Romisch, Steven R. Jefferts, Victor S. Zhang, Thomas E. Parker, Neil Ashby, P Adamson, G. Barr, A. Habig, J Meier, C. James, R. Nicol, R. Plunkett, C. Rosenfeld, Russell Bumgarner, M. Christensen, Jonathan Hirschauer, Blair Fonville, Demetrios Matsakis, Ed Powers, J. Wright, Angela Mckinley
In the context of time-of-flight measurements, the timing at the departure and arrival locations is obviously critical to the outcome of the experiment. In the case of neutrino time-of-flight experiments, the locations are many hundreds of kilometers apart

Observations of Pt/Ne hollow cathode lamps similar to those used on the Cosmic Origins Spectrograph

July 7, 2008
Author(s)
Gillian Nave, Craig J. Sansonetti, S. V. Penton, Nathaniel Cunningham, Matthew Beasley, Steve Osterman, F Kerber, Charles D. Keyes, Michael R. Rosa
… spectra of the air-aged lamp were taken after 206 h, 500 h, 778 h, 783 h and 897 h of operation. Spectra of the vacuum-aged lamps were taken after 500 h for both lamps, and after 1000 h for one of the lamps. … three lamps, total output dropped by less than 15 % over 500 h. We conclude that the lamps satisfy the requirements of …
