A PMT (Photomultiplier Tube) assembly is a component used in scintillation detectors to detect and measure ionizing radiation. PMTs consist of a photocathode, a series of dynodes, and an anode. When a photon strikes the photocathode, it releases electrons through the photoelectric effect. These electrons are then accelerated and multiplied as they pass through the series of dynodes. Finally, the multiplied electrons reach the anode, generating an electrical pulse. 

For GOHI Photomultiplier tube, it can be assembled with different scintillation crystal, like NaI, CsI, BGO, LaBr3, CeBr3 and plastic scintillation. We can offer a variety of assemble options in terms of scintillators size, type of PMT, coupling grease, magnetic shielding and dismountable configurations between scintillators and PMTs, and our manufacturing process ensures the detectors with high sensitivity, high stability and excellent resolution.

Below are some NaI standard size detector for reference, more options and customization request please contact us by: info@whgohi.com 

Besides,  we can also offer the integrated scintillation detector which include a scintillator, photomultiplifier tube(PMT) , voltage divider, built-in high voltage module and preamplifier  with connectors BNC, SHV, MHV or 4 Pins etc. Detectors design is flexible and user friendly, which can be used for the construction of different photon counters or nuclear radiation detectors.
