Escape peak form, as in gas-flow detectors, when an incoming X-ray produces a characteristic X-ray from the detector material. These X-rays are produced near the surface of the detector crystal and if they are reabsorbed there is no problem. If, however, the X-ray "escapes" the detector, an escape peak is produced. The escape peaks in a Si(Li) detector are 1. 74 keV lower in energy that the incident X-rays(Ec for Si-Ka). Escape peaks will be present for all parent peaks above 1. 84 keV(the Si absorption edge), and their magnitudes are usually a few percent of the parent peak. 1, record 2, English, - escape%20peak

Le porte-échantillon est connecté à un moteur pas-à-pas commandé par un ordinateur. Il permet ainsi d'analyser plusieurs échantillons sans pour cela casser le vide maintenu dans la chambre. Les rayonnements X ont été mesurés à l'aide d'un dispositif comprenant : un détecteur LEGe (low energy germanium); un préamplificateur de charges à faible bruit de fond; un amplificateur qui assure une nouvelle amplification et une mise en forme des impulsions. Le pic de la raie X K caractéristique du phosphore correspond aussi au pic d'échappement du silicium de la raie X K du calcium. Le remplacement du détecteur Si(Li) par un détecteur LEGe permet de réduire cette interférence. 1, record 2, French, - pic%20d%27%C3%A9chappement

The absorption coefficient of a material is ideally the fraction of the randomly incident sound power which is absorbed, or otherwise not reflected. It can be determined in two main ways, and there are often variations in the results depending upon the method of measurement chosen. It is standard practice to measure the coefficient at the preferred octave frequencies over the range of at least 125 Hz-4 kHz. For the purposes of architectural design, the Sabine coefficient(calculated from reverberation chamber measurement) is preferred. Interestingly, some absorbent materials are found to have a Sabine coefficient in excess of unity at higher frequencies. This is due to edge effects and, when this occurs, the value can be taken as 1. 0. 4, record 3, English, - Sabine%20absorption%20coefficient

Reverberation Time. This formula was developed by W.C. Sabin in the late 19th century. The Sabin unit is a measurement of absorption in the range 0 to 1, an absorption coefficient of 0 indicates a material that reflects sound totally, and a coefficient of 1, a material that adsorbs sound totally. 3, record 3, English, - Sabine%20absorption%20coefficient

L'absorption à une fréquence déterminée est définie par le facteur ou coefficient d'absorption qui est le rapport de l'énergie sonore absorbée par une surface S du matériau à l'énergie qui vient la frapper. Il ne faut pas confondre ce coefficient d'absorption avec le coefficient de Sabine obtenu par des mesures d'absorption faites en salles réverbérantes. 5, record 3, French, - facteur%20de%20Sabine

Incident X-ray photons are converted in the scintillator into bursts of visible light photons, some of which fall on the photocathode and can be measured. For incident photons having energies higher than the absorption edge of the elements contained in the scintillator, an escape peak can be observed. 3, record 4, English, - scintillation%20counter
