Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
  • Scientific Instruments
CONT

Eppley Precision Spectral Pyranometer, PSP. This instrument is considered to be the most accurate radiometer produced commercially for the measurement of global sun and sky radiation, totally or in defined wavelength bands. It can be inverted to measure reflected shortwave radiation(from which the albedo can be calculated). The PSP has a circular multi-junction thermopile of the plated(copper-constantan) wire wound type which is temperature compensated in order to get a response that is independent of ambient temperature. The temperature sensed by the detector is nearly linear with the flux density of incident radiation. The instrument is supplied with a pair of removable precision ground and polished concentric hemispheres of Schott optical glass. The inner hemisphere is transparent to a wavelength of 0. 285-2. 800 µm. The outer dome can be replaced by Schott glass hemispherical filters which transmit within specified bandwidths. Desiccant is placed in the side of the instrument to absorb humidity inside the glass domes. Measurements are reported in Wm-2.

CONT

The Eppley PSP (or simply Eppley Pyranometer) is an instrument for the measurement of radiation in the range approximately between 285 and 2800 nm. As noted earlier, this wavelength range is commonly referred to as shortwave radiation, and it’s primary source is the sun.

Record 4 2009-09-18

English

Subject field(s)
  • Scientific Instruments
  • Atomic Physics
OBS

Each measurement channel has, inside the nuclear reactor core, an instrumentation tube of a fuel assembly and a thimble placed inside the instrumentation tube, in which the fission probe moves around. Neutron flux measurements are carried out in a set of fuel assemblies distributed throughout the core cross section.

French

Domaine(s)
  • Instruments scientifiques
  • Physique atomique
CONT

Les détecteurs mobiles sont du type chambres à fission. Ce type de capteur neutronique est une chambre d'ionisation classique et utilise comme matière sensible aux neutrons, l'uranium. Celui-ci, enrichi à 90 % en uranium 235, est déposé sous forme d'une couche d'oxyde. Chaque détecteur [...] est constitué d'une électrode centrale (anode), d'une deuxième électrode (cathode) qui détermine le volume de mesure, et d'une enveloppe de protection externe. Le gaz de remplissage est l'argon.

English

Subject field(s)
  • Pipes and Fittings
  • Energy Transformation
  • Nuclear Fission Reactors
CONT

To obtain a more exact representation of the neutron flux distribution within the core, additional neutron flux measurements are conducted within the core... Each incore probe is fixed to the end of a flexible cable referred to as a teleflex cable for moving it inside a measuring channel of the instrumentation of the nuclear reactor. Each measuring channel opens at one end into an instrumentation area in the bottom part of the reactor building. The fission probes are moved inside the measuring channels from the instrumentation area. Each measuring channel includes a fuel assembly instrumentation tube inside the core of the nuclear reactor and a glove finger inside the instrumentation tube in which the fission probe moves. The neutron flux is measured in a set of fuel assemblies distributed throughout the section of the core.

Record 6 2003-06-17

English

Subject field(s)
  • Orbital Stations
CONT

DOSTEL as a telescope is used for the measurement of time dependent LET [Linear Energy Transfer] spectra separately for galactic cosmic particles and trapped particles in different directions at defined shielding locations. DOSTEL is used as reference instrument for the MDUs [Mobile Dosimetry Units]. The MDUs are designed as small lightweight personal dosimeters but may be used also at different locations inside the spacecraft. The measurement set is completed by an onboard small compact TLD-Reader [Thermoluminescence Dosimetry] for the study of spatial distribution and time dependence of absorbed doses and for neutron dose measurements. The whole dosimetry set shall be used for routine environmental, individual and EVA [Extra Vehicular Activity] dosimetry. The single detector systems complement each other in their recording characteristics.

OBS

DOSTEL: initialism for DOSimetry TELescope.

OBS

dosimetric telescope; DOSTEL: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

  • Scientific Research Equipment

CONT

The Surface Science Package consists of nine independent sensor subsystems with the primary aim of characterising Titan's surface at the end of Huygens’ descent through Titan's atmosphere. In addition, many useful atmospheric measurements will be performed during the descent phase. Seven sensors are mounted inside or on the lower rim of a cavity in the Probe's foredome, and are thus exposed to Titan atmosphere or surface material. Two sensors which do not require direct exposure to the atmosphere or surface are mounted on the electronics box inside the descent module.

DEF

Hypothesis that stratospheric ozone depletion in due to the presence of chlorinated substances.

CONT

Susan Solomon reported that the NOAA team's UV spectrophotometer found nitrogen dioxide levels inside the ozone hole that are the lowest the group has observed anywhere in the world, which would support the chlorine theories. The JPL team's infrared measurements of nitric acid have yet to be analyzed. But the concentrations of one active chlorine species seem low, and another high.

Les produits chlorés qui proviennent de la photodécomposition stratosphérique des chlorofluorocarbures, viennent confirmer l'hypothèse que ce sont des produits chimiques anthropiques et non la dynamique de la stratosphère, qui sont responsables de la disparition de l'ozone.
