PHOTOMULTIPLIER TUBES

These photomultipliers can be manufactured of low-background materials. In this case, the PMT own radioactivity in the energy range of 50 - 3000 keV is not more than 0.05 - 0.3 pulse/sec Purpose Conversion of weak input light signal into an electric signal Features Wide spectral response range from UV up to near-IR High sensitivity up to single photon counting due to the process of secondary emission Fast time response and low noise Capability of operation under conditions of intensive magnetic and radioactive fields as well as at high temperatures Applications Photometry and spectroscopy for weak light signals Ecology, biophysics, medicine, etc. Nuclear physics, high energy physics, etc. Geology, geophysics, etc.
