English

Subject field(s)
  • Measuring Instruments
  • Radiological Physics (Theory and Application)
CONT

The planar detector consists of a crystal of either rectangular or circular cross section and a sensitive thickness of 1-20 mm... The electric field is perpendicular to the cross-sectional area of the crystal. The crystal thickness is selected on the basis of the gamma-ray energy region relevant to the application of interest, with the small thicknesses optimum for low-energy measurements(for example in the L-x-ray region for special nuclear material). Planar detectors usually achieve the best energy resolution, because of their low capacitance; they are preferred for detailed spectroscopy, such as the analysis of the complex low-energy gamma-ray and x-ray spectra of uranium and plutonium.

OBS

Solid-state detectors are produced mainly in two configurations: planar and coaxial. These terms refer to the detector crystal shape and the manner in which it is wired into the detector circuit.

French

Domaine(s)
  • Appareils de mesure
  • Physique radiologique et applications
OBS

Détecteurs réalisés selon la technique d’implantation ionique «planaire». La technologie de fabrication des détecteurs [au] silicium a beaucoup évolué au cours du dernier demi-siècle grâce aux progrès de la microélectronique. Aujourd’hui, on utilise le procédé d’implantation passivée planaire (ou Implantation Planar Process) qui a complètement supplanté les techniques de fabrication des détecteurs à barrière de surface ou à jonction diffusée. La technique actuelle basée sur l’utilisation d’implanteurs (accélérateurs d’ions de faible énergie), permet de réaliser des jonctions abruptes et minces grâce à un contrôle très précis de la position en profondeur des dopants (B pour type P et As pour type N) à l’intérieur d’un substrat de Si (réduction de la zone morte du dispositif) de haute résistivité (de type N–). Celui-ci est recouvert d’une couche mince de passivation (SiO2) afin de minimiser les courants de fuite de surface. Un traitement chimique par photolithographie permet de définir la géométrie finale du détecteur.

DEF

The difference between the original cross sectional area of a tension test specimen and the area of its smallest cross section... The reduction of area is usually expressed as a percentage of the original cross sectional area of the specimen.

OBS

Many English authors make no difference between "reduction of area" which is a phenomenon and "percent reduction of area" which is a mathematical value.

This truss segment, called "P1," is a 46-by-15 foot structure weighing about 32,000 pounds when fully outfitted and ready for launch.

CONT

The P1 Truss, the first port truss segment, was attached to the port side of the S0 truss ... The P1 Truss provides structural support for the Active Thermal Control System, Mobile Transporter and one Crew and Equipment Translation Aid cart. ... The P1 Truss also has mounts for cameras and lights, and antenna support equipment for both UHF [Ultra High Frequency] and S-band communications equipment. The S-band equipment is currently on the P6 Truss.

CONT

The main truss segments-S0, P1, S1, P3, and S3-were designed as rigid hexagonal sections; a six-point structure is more rigid than one with four points. The hexagonal cross section also maximizes the volume that can be used to load equipment onto the truss. A square will not use the available volume as well as a hexagon.... The truss segments are not regular hexagons; the sides are not equal in length. The segments are wider than they are tall to further exploit the Shuttle payload bay area...
