Photomultipliers

The PhotoMultiplier Tube(PMT) uses an external photoelectric effect in combination with a secondary electron emission effect to detect radiation. It is a vacuum tube containing a photocathode, a series of amplifying electrodes (called a dynode) and an anode. The photomultiplier tubes provide extremely high sensitivity and fast response. The spectral sensitivity range of the PMT is from about 120 nm to 1700 nm. However, there is no PMT that covers this entire range.

One of the largest photomultiplier manufacturers is Hamamatsu, which offers special PMT detectors in addition to standard photomultipliers.

There are two main groups of PMT detectors:

  • Stand-alone photomultiplier tubes
  • PMT modules integrating photomultiplier, power supply circuit and voltage divider into one housing

Key features

  • Wide selection (different types of PMT detectors + rich accessories)
  • High sensitivity
  • Fast response
  • High gain (resulting amplification effect even several million)
  • low noise
  • wide spectral response

Parameters

Types of photomultiplier tubes

Hamamatsu photomultipliers are divided into several categories for clarity:

These photomultipliers receive incident light through the front surface of the glass tube. Their photocathode operates in transmission mode and is placed directly on the inner surface of the entrance window. As a result, the detector provides better spatial uniformity than PMT sensors with a photocathode operating in the reflectance mode.

Side-on type photomultipliers receive incident light through the side of a glass tube. Because of their design, they are widely used in spectrophotometers and universal photometric systems.

These photomultipliers can provide very fast response due to the special metal channel structure of the dynode. They are suitable for position-sensitive measurements.

MCP PMTs dominate with their high-speed time response (picosecond level). Instead of conventional discrete dynodes, they contain a microchannel plate. Electrons from the photocathode enter individual channels, in which the original number of photoelectrons subsequently increases due to the secondary emission process.

PMTs with high quantum efficiency, PMTs with special tube shape, PMTs for magnetic field measurements, ...

PMT modules

PMT modules integrate into a single housing a photomultiplier (realizes the conversion of light into electrical signals), a high-voltage power supply circuit and a voltage divider (determines the distribution of the applied voltage between the respective dynodes).
