The Bragg Crystal Spectrometer(BCS) is designed to study plasma heating and dynamics during the impulsive phase of solar flares. It consists of two bent crystal spectrometers, BCS-A and BCS-B, that observe the H-like line complex of Fe XXVI, and He-like complexes of Fe XXV, Ca XIX and S XV. Each spectrometer consists of a double detector placed behind a pair of germanium crystals that diffract the incoming X-rays into the detectors. The two structures are mounted at the front of the Yohkoh spacecraft, on either side of the central panel, with a thermal filter mounted in front of each spectrometer. The crystal dispersion axes are oriented north-south.  2, fiche 2, Anglais, - Bragg%2Dcrystal%20spectrometer

Indiana University Laboratory for Spectrochemistry. Plasma Source Mass Spectrometry. "Single-Crystal Scintillator-Based Array Detector for Sector-Field Mass Spectrometry, "[by] David A. Solyom. Beginning with the use of photographic plates in the first quarter of this century, array detectors have had a long history of usage in mass-spectrometric analysis. Array detectors are position-sensitive devices capable of independently measuring ion signals that are incident at different locations on the detector's face. Currently popular among the different types of array detectors available for mass spectrometry are microchannel-plate(s)(MCP) coupled with a phosphor.... The electrons emitted from the rear of the MCP strike the phosphor being held in close proximity(1mm) to the MCP. The phosphor screen is sensitive to the incident electrons and will emit photons in response. The number of emitted photons is proportional to the number of incident electrons and the location on the phosphor from which the photons are emitted coincides with the location of the incident electrons. The photons from the phosphor can then be converted into a proportional electronic signal by an imaging device such as a CCD or CID detector array.  2, fiche 4, Anglais, - sector%20field%20mass%20spectrometry

Il existe plusieurs traductions du terme «inductively coupled plasma (ICP)» : le plus proche de la description de la technique est «plasma induit par un courant de haute fréquence», le plus simple est «torche à plasma»; pour décrire un «sector field mass spectrometer» nous parlons de «spectromètre de masse à secteur magnétique» ou, plus brièvement, de «spectromètre de masse magnétique». L'équivalent français de ICP-SFMS serait donc «torche à plasma couplée à un spectromètre de masse magnétique» (version courte) ou «plasma induit par un courant de haute fréquence associé à un spectromètre de masse à secteur magnétique» (version longue).

The lack of margins in selectivity and the sensitivity of etching rates to other variables such as loading (i.e., the total area to be etched) in plasma etching have made it necessary to develop a positive means of determining the moment etching should stop, rather than relying of fixed times. Most end-point detectors developed to date are based on gas analysis of one sort or another. They determine the instant that either the material being etched has largely disappeared or the material beneath that layer is being attacked. Detecting spectral lines in the plasma related to a particular reaction product is the simplest way, but it cannot be employed in all cases.  1, fiche 8, Anglais, - plasma%20end%2Dpoint%20detector

Positively or negatively charged ions entering the sensor are first detected by the charge that they induce when they fly through the entrance grid. This charge signal will only be evaluated if the ion subsequently impacts the impact plasma detector. Dust particles(charged or uncharged) are detected by the plasma produced during the impact on the gold target of the sensor.  2, fiche 9, Anglais, - impact%20plasma%20detector
