Download citation | method for the determination of photomultiplier collection efficiency, f | photomultiplier collection efficiency, f, is a fundamental, but difficult, parameter to measure with. A photomultiplier tube (pmt) consists of a photosensitive cathode, several dynodes and a collection anode. the dynodes are responsible for the increase in signal by electron multiplication. pmts see the elemental line intensity per unit time proportionally with current and have wide dynamic ranges. The relative collection efficiency (ce) of 20 inch photomultiplier tubes (pmts) cannot be measured directly, but it can be obtained by the quantum efficiency (qe) of the photocathode and the relative detection efficiency (de) of the pmts. the measurements of relative ce and its spherical uniformity of the 20 inch pmts have been introduced in. Good collection efficiency, good uniformity (3) box and linear focused type good collection efficiency, good uniformity, low profile (4) circular and linear focused type fast time response, compactness (5) venetian blind type good uniformity, large output current (6) fine mesh type high immunity to magnetic fields, good uniformity, high pulse. Photomultiplier tube basics 9 the photocathode the response of a pmt to light is specified by its photocathode sensitivity which can be specified by several ways: quantum efficiency, integral quantum efficiency, cathode radiant sensitivity, cathode luminous sensitivity and cathode blue sensitivity. quantum efficiency (%).

Quantum efficiency curves photek offers a full range of second generation photocathodes. these include csi, solar blind, bialkali, low noise s20, s20 and s25 which demonstrate the broad spectral response that can be achieved, as seen below: photomultiplier tube datasheet. The relative collection efficiency (ce) of 20 inch photomultiplier tubes (pmts) cannot be measured directly, but it can be obtained by the quantum efficiency (qe) of the photocathode and the relative detection efficiency (de) of the pmts. Owning to the serious loss of photoelectrons striking at the input electrode of traditional microchannel plate (mcp), photoelectron collection efficiency (ce) of photomultiplier tubes based on mcp (mcp pmts) fluctuates around the mcp open area fraction and cannot make a breakthrough.
