Protective surface coatings on semiconductor nuclear radiation detectors

Description: Surface states on germanium p-i-n junctions have been investigated using deep level transient spectroscopy (DLTS) and collimated beams of 60 keV gamma-rays. The DLTS spectra have a characteristic signature for each surface treatment but the spectra are complex and not readily interpretable as to suitability for radiation detectors. Collimated gamma-ray beams give a direct measure of surface channel effects and typeness. Hydrogenated amorphous germanium (a-Ge:H) was explored as a surface layer t… more

Centroid finding method for position-sensitive detectors

Description: A new centroid finding method for all detectors where the signal charge is collected or induced on strips of wires, or on subdivided resistive electrodes, is presented. The centroid of charge is determined by convolution of the sequentially switched outputs from these subdivisions or from the strips with a linear centroid finding filter. The position line width is inversely proportional to N/sup 3/2/, where N is the number of subdivisions.

New parameterization of the E1 gamma-ray strength function

Description: The giant dipole (GD) parameters of peak energy, width, and cross section were satisfactorily correlated for elements from V to Bi, assuming two overlapping peaks with a separation dependent on deformation. The energy dependence of the GD resonance is assumed to have a Breit-Wigner form, but with an energy-dependent width. The resulting gamma-ray strength function model is used to predict neutron capture cross sections and gamma-ray spectra for isotopes of Ta, Os, and Au. 23 references.

DIII neutral beam shielding

Description: It appears that neutral beam heating will be the most viable method of raising the temperature of a plasma for some time to come. In fact, neutral beams may continue to be one stage of the heating program indefinitely. However, the external field, called the fringe field, of a Tokamak can impair the effectiveness and operation of the ion source and beam. Remember, a Tokamak is a large, air-core transformer coupled with a solenoid. The design process is summarized from start to finish. The sourc… more

Storage of heat and coolth in hollow-core concrete slabs. Swedish experience, and application to large, American-style buildings

Description: The Folksam office building in Farsta, near Stockholm, has operated since December 1977 with an energy use for direct space heating of only 60 kWh/m/sup 2/ (19,000 Btu/ft/sup 2/), which is only half the Stockholm average for new buildings. To this 60 kWh/m/sup 2/ must be added the typical electric use of another 60 kWh/m/sup 2/ for lights, equipment, fans, etc. Even though Stockholm has 3580 deg-day (C), new Swedish buildings are so well insulated that their temperature floats upwards during mo… more

Characterization of discontinuities in the Stripa granite

Description: Characterization of the fracture system in a repository is important, and its purpose should dictate the scale over which measurements must be made. The results discussed pertain to nearfield behavior of a rock mass and represent a practical limit to the degree to which discrete subsurface discontinuities can be defined by surface mapping and cross-correlation of observational borehole data. Discontinuities on the scale of the rock mass being studied can dominate its response, and should theref… more
