Direction-Sensitive Hand-Held Gamma-Ray Spectrometer. SciTech Connect. Mukhopadhyay, S. A novel, light-weight, hand-held gamma-ray detector with directional sensitivity is being designed. The detector uses a set of multiple rings around two cylindrical surfaces, which provides precise location of two interaction points on two. The Q factor or quality factor is a dimensionless parameter that describes how under-damped an oscillator or resonator is, or equivalently, characterizes a resonator's bandwidth relative to its center frequency. Higher Q indicates a lower rate of energy loss relative to the stored energy of the oscillator, i.e., the oscillations die out more slowly.

Scott Hubbard. The linearity and stability of 6 LiI(Eu) (L) were simultaneously inspected with a multi-line Ra source emitting γ radiation from to keV.
The measurement lasted more than 10 hours. ADVERTISEMENTS: Some of the important types of Spectroscopic Techniques are as follows: Type # 1.
Gamma Spectroscopy: Gamma spectroscopy is a radionuclide measurement method. While a Geiger counter determines only the count rate, a gamma spectrometer will determine the energy and the count rate of gamma-rays emitted by radioactive substances. Gamma.

The Messenger is published by the European Southern Observatory (ESO), the foremost intergovernmental astronomy organisation in Europe, in hardcopy and electronic form, four times a year: in March. These questions are addressed with a high-resolution near and far UV imaging spectrometer sensitive to emission from plasma at temperatures between 5, K and 10 MK.
IRIS has a field-of-view of arcsec, a spatial resolution of arcsec, and velocity resolution of km/s. 2 Physics of the Cosmos Annual Technology Report The report cover reflects the breadth of science topics pursued by the Physics of the Cosmos Program.
Modern astrophysics has expa. Multivariate methods have been developed to assist in the interpretation of multiwavelength spectral data. When carrying out an elemental analysis by optical emission spectrometry, the analyst is faced with a choice of many spectral lines on which to base the analysis.
The problem of choosing a suitable line depends upon other components in the sample, as some of these. A millimeter-wave survey over half the sky, that spans frequencies in the range of 30 to GHz, and that is both an order of magnitude deeper and of higher-resolution than currently funded surveys would yield an enormous gain in understanding of both.

The measurement of diffuse PeV gamma-ray emission from the Galactic plane would provide information about the energy spectrum and propagation of Galactic cosmic rays, and the detection of a point-like source of PeV gamma rays would be strong evidence for a Galactic source capable of accelerating cosmic rays up to at least a few PeV.

We found that our hollow-cathode lamps are suitable for precise wavelength calibration, but their spectra contain a number of lines of neon or argon that are so bright that the lamps cannot be used in.
