Daly tajur

Daly detector

gaasifaasi ioontajur, mis koosneb metallist „uksenupust“, stsintillaatorist (fosforekraanist) ja fotokordistist, ja seda kasutatakse tavaliselt massispektrimõõturites

gas-phase ion detector that consists of a metal "doorknob", a scintillator (phosphor screen) and a photomultiplier, and typically used in mass spectrometers

Daly tajur

Usage examples

Daly tajuri eeliseks on see, et fotokordisti saab eraldada aknaga, mis laseb footonid massispektrimõõturi kõrgvaakumist läbi, vältides seeläbi muidu võimalikku saastumist ja pikendades tajuri eluiga.

Daly detector

Usage examples

The advantage of the Daly detector is that the photomultiplier can be separated by a window, which lets the photons through from the high vacuum of the mass spectrometer, thus preventing an otherwise possible contamination and extending life span of the detector.
