WebA PMT can detect a single arriving photon, and emit a single photo-electron, with about 85% max quantum efficiency depending on the frequency of the photon, and the PMT cathode material. WebMeasurements such as excitation-emission maps are therefore much faster with a CCD compared to standard photomultiplier tube (PMT) detectors. In addition, this enables the …

Are CCDs approaching the sensitivity of photomultiplier tubes?

WebMay 1, 2001 · The PMT has fewer pixels, by orders of magnitude, than a standard CCD detector. The multiple-anode PMT, however, has time-response in the gigahertz range, while the CCD detector has a frame rate in the 100-Hz range. It is this dual capability (spatial and temporal) of the multiple-anode PMT that makes it such a desirable and unique detector. WebThe diagram shows one column of a CCD with an over-exposed stellar image focused on one pixel. The channel stops shown in yellow prevent the charge spreading sideways. The charge confinement provided by the electrodes is less so the charge spreads vertically up and down a column. The capacity of a CCD pixel is known as the ‘Full Well’.
