1. The output of the monochromator was detected by a photomultiplier, amplified and then plotted on a wavelength-synchronized x-y recorder.
2. When the compensation was exact the absorption of the photons by the thin layer of 57 Fe was maximized and the counting rate on the photomultiplier behind it was minimized.
3. The absorber covered a scintillator which was viewed by a photomultiplier.
4. This is then amplified by photomultiplier tubes and converted into electrical impulses.
5. Plots of luminescence intensity against wavelength thus obtained must be corrected for any variations in spectral response of optical fibre, monochromator and photomultiplier.
6. The photomultiplier was operated in the single photon counting mode.
7. Light was detected by an EMI 9813B photomultiplier in an EMI FACT 50 MK III cooler, cooled to -20C and operated at 1375 volts.
8. The measuring cell is immersed in a vat of liquid, usually benzene or xylene which can be thermostatted at temperatures between 273 and 400 K. Scattering is detected by a photomultiplier, capable of revolving round the cell and the intensity is recorded on a galvanometer.
9. The TL produced by archaeological samples such as pottery is weak and its measurement therefore requires sensitive light-detecting equipment such as a photomultiplier, which converts the light signal to an electrical one.
10. Malkin, Ford and Fork also used a photomultiplier device.
11. Detection is usually electrical, with a photomultiplier.
12. Since one usually needs to measure emission from only a small area of the viewing field rather than the whole field, a fibre-optic probe inserted in the light path would probably be the best method, with the light-pipe output directed on to a highly sensitive photoelectric cell or photomultiplier, whose output would also have to be calibrated against some standard phosphor.
13. Fork, Ford and Catanzaro used a fluorescence spectrophotometer based on a gallium arsenide photomultiplier.
