Portrait of William "Bill" E. Burr
No full textBurr joined NIST in 1978. He was the lead author of the influential NIST Special Publication 800–63, "Electronic Authentication Guideline." Burr is attributed with creating guidelines for passwords that include changing passwords every 90 days, and using a password with a combination of capital letters, numbers, and symbols
The fundamental neutron physics beamline at the spallation neutron source
No full textThe Spallation Neutron Source (SNS), currently under construction at Oak Ridge National Laboratory with an anticipated start-up in early 2006, will provide the most intense pulsed beams of cold neutrons in the world. At a projected power of 1.4 MW, the time averaged fluxes and fluences of the SNS will approach those of high flux reactors. One of the flight paths on the cold, coupled moderator will be devoted to fundamental neutron physics. The fundamental neutron physics beamline is anticipated to include two beam-lines; a broad band cold beam, and a monochromatic beam of 0.89 nm neutrons for ultracold neutron (UCN) experiments. The fundamental neutron physics beamline will be operated as a user facility with experiment selection based on a peer reviewed proposal process. An initial program of five experiments in neutron decay, hadronic weak interaction and time reversal symmetry violation have been proposed
The "median" method for the reduction of noise and trigger jitter on waveform data
No full textThe "median" method for the reduction of the effect of noise and trigger jitter on waveform data is described. The effectiveness of this method was examined using simulations and experiments and, for typical jitter and noise observed in electrical pulse metrology, is shown to provide reconstructed waveforms with transition durations that accurately match those of the input signal. Also, for aberrations, an upper bound on the error in the amplitude of the aberration is provided
Parity-violating neutron spin rotation in a liquid parahydrogen target
No full textOur understanding of hadronic parity violation is far from clear despite nearly 50 years of theoretical and experimental progress. Measurements of low-energy parity-violating observables in nuclear systems are the only accessible means to study the flavor-conserving weak hadronic interaction. To reduce the uncertainties from nuclear effects, experiments in the few and two-body system are essential. The parity-violating rotation of the transverse neutron polarization vector about the momentum axis as the neutrons traverse a target material has been measured in heavy nuclei and few nucleon systems using reactor cold neutron sources. We describe here an experiment to measure the neutron spin-rotation in a parahydrogen target (n-p system) using pulsed cold-neutrons from the fundamental symmetries beam line at the Spallation Neutron Source under construction at the Oak Ridge National Laboratory
Search for radiative beta-decay of the free neutron
No full textResults of the first experiment to search for the radiative decay mode of the free neutron are reported. The gamma-spectrum was studied in the energy region from 35 keV to 100 keV in six Cs(T1) scintillators, each set at an angle of 35 to, and shielded from, a central plastic scintillator electron detector. Triple coincidences were recorded with recoil protons detected in a micro-channel plate. A limit for the branching ratio BR <6.9x10(-3) (90% confidence level) was obtained, which is greater that the theoretical prediction by not more than a few tenths of a percent
