The upper water layer of the ocean contains air bubbles, induced by wind and waves. These air bubbles attenuate the sound transmission and reception from a hull-mounted transducer... The thickness of the bubble layer may be 5-10 m, or more, depending on the sea state. A towed transducer operates below this bubble layer. The transducer is closer to the fish. This gives a better signal to noise ratio, and also the resolution of single fish is improved because the width of the sound beam is smaller. For the study of deep water biological resources[, ] below 500 m[, ] a towed transducer is essential.  2, record 1, English, - towed%20transducer

... the scanning ion-conductance microscope (SICM) ... scans a sample not with a metal or diamond tip but with a glass micropipette containing a tiny electrode. The workers immerse the sample and the pipette in a bath of electrolyte (such as a salt solution) and establish a voltage difference between the electrode within the pipette and another electrode in the bath. A current of ions tends to flow between the electrodes by way of the pipette opening, but when the pipette approaches the surface of the sample, the current weakens. It disappears altogether when the scanned pipette touches the sample, which blocks the opening. Equipped with a feedback mechanism that maintains a constant ion current through the pipette opening, the SICM can profile a sample’s topography. The fineness of the pipette does limit the SICM’s resolution to about .2 micron (10 nanometers may eventually be feasible).  3, record 3, English, - scanning%20ion%2Dconductance%20microscope

The device is therefore best suited to more specialized functions-studying a living cell' s electrical behavior, for example.

Pole-zero cancellation(Tail cancellation) … we approximated the preamp output pulse as a step function, however, in a real preamp pulse, the falling tail is a long exponential decay instead of a simple step function. Consequently, there is a small amplitude undershoot starting at about 7τ. This undershoot decays back to baseline with the long time constant of the preamplifier. At medium to high counting rates, a substantial fraction of the amplifier output pulses will ride on the undershoot from a previous pulse. The apparent pulse amplitudes measured for these pulses will be significantly lower, which deteriorates the energy resolution. Most shaping amplifiers incorporate a pole-zero cancellation circuit to eliminate this undershoot. The benefit of pole-zero cancellation is improved peak shapes and resolution in the energy spectrum at high counting rates.  1, record 5, English, - %20pole%2Dzero%20cancellation%20circuit

Au lieu de partir de la ligne de base, un signal va donc débuter sur la queue d’un signal précédent, c’est-à-dire sur une valeur légèrement négative.

The performance of all the Voyager Workstations is improved by addition of our proprietary Delayed Extraction(DE) technology. By introducing a time delay between ionization of the sample and extraction of the ion from the source, adduct ions can be separated from the ion of interest prior to entry into the flight tube. This is especially important for analysis of oligonucleotides and glycoproteins, which tend to bind to matrix molecules. The effect is a reduction in chemical noise. Higher signal-to-noise ratios are achieved along with greatly improved resolution.  3, record 6, English, - delayed%20extraction%20technology

The Very High Resolution Spectrometer. The 6. 65 m off-plane Eagle spectrometer connected to the Synchrotron Ultraviolet Radiation Facility(SURF II) electron storage ring at the National Institute of Standards and Technology(NIST) is one of the two very high resolution spectrometers(VHRS) in the world that combine a synchrotron radiation light source with photoelectric detection of vacuum ultraviolet spectra. Spectra are obtained over a usable range from approximately 20 nm to 200 nm by scanning the exit slit of the spectrometer at wavelength intervals as small as 0. 1 pm in first order. The beamline leading to the entrance slit of the VHRS includes three cylindrical uncoated glass mirrors with incident angles of 80, 70, and 80 degrees from the normal to provide a converging beam to match the f/number of the instrument which is about f/50. Since 1990, when the three-mirror light collection system was improved, a number of high resolution measurements have been made in the region between 40 nm and 120 nm.  2, record 14, English, - very%20high%20resolution%20spectrometer

Ultra High Resolution Spectrometer(UHRS).... Laser spectroscopy has stimulated the development of spectrometers with improved performance and has led SOPRA to develop a new line of monochromators with ultra-high resolution. SOPRA has designed the mechanical parts in the most careful way to take the best advantage of the newest diffraction gratings. The instrument function of a monochromator is defined by the product :Resolution X Luminosity/Noise=RL/N. The resolution R directly depends on the diffraction grating and the focal length. The luminosity L depends on the area, on the efficiency of the grating, and on the slits. The noise N is essentially caused by the light scattered by the grating through the output slit and it diminishes when the focal length is increased. Another crucial quality factor of a monochromator is the ease to use it, i. e. its stability and reproducibility with regard to resolution and luminosity, and its tuning characteristics.  1, record 15, English, - ultra%20high%20resolution%20spectrometer
