Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Undergraduate education in nuclear engineering in the USA
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1993-06)
The discipline of nuclear engineering is described, giving some historical background to explain the structure of the curricula commonly found in nuclear engineering programs in the U.S. Typical curricula are described, ...
The influence of a plane boundary on the thermophoretic force in the knudsen regime
(Elsevier, 1987-05)
The effect of a plane diffusely reflecting wall on the thermophoretic force acting on a particle in the Knudsen regime is investigated. A general expression for the force on a particle in a nonuniform gas is given and then ...
Radiation Detectors for X-Ray and Gamma-Ray Spectroscopy
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-01)
The detectors used primarily for the measurement of X-rays and gamma-rays are discussed because of their predominance in analytical measurements, and having the most dramatic improvements.
Digital signal processing and zero-dead-time counting
(Kluwer Academic Publishers; Kluwer Academic Publishers/Akadémiai Kiadó ; Springer Science+Business Media, 2001-05)
One of the most recent developments in equipment for high and/or varying count rates, as encountered in the gamma-ray spectrometry needed for INAA via short-lived radionuclides, is the advent of EG&G Ortec's DSPECplus™. ...
Soft X-ray emission from a CO 2 laser-heated Z-pinch plasma
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1987-09)
We report results of soft X-ray measurements in which a high-power (10 10 –10 11 W/cm 2 ) CO 2 laser was used to heat a near critical density (<10 19 cm −3 ) helium Z-pinch plasma. Frequency-integrated X-ray data show that ...
Cold neutron prompt gamma activation analysis at nist: A progress report
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1995-02)
Neutron captue prompt gamma-ray activation analysis at the NIST Cold Neutron Research Facility
(Kluwer Academic Publishers; Akadémiai Kiadó ; Springer Science+Business Media, 1993-01)
An instrument for neutron capture prompt gamma-ray activation analysis (PGAA) has been constructed as part of the Cold Neutron Research Facility at the 20 MW National Institute of Standards and Technology Research Reactor. ...
Production of XeO * in a CW microwave discharge
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1989-12)
A low-power CW microwave discharge at 2.45 GHz was used to produce XeO * excimer molecules. It was found that a total gas pressure between 5 and 20 Torr, absorbed power of about 20–100 W, and an oxygen-to-xenon ratio of ...
The half-life of 76 As
(Kluwer Academic Publishers; Kluwer Academic Publishers/Akadémiai Kiadó ; Springer Science+Business Media, 2003-09)
In the course of making high-accuracy measurements of arsenic, we found that the most recently published and compiled half-life of 76 As did not agree with our data as well as the earlier accepted value. To redetermine ...
