PMT (Photomultiplier Tube)

在光感測器領域,光電倍增管PMT已知具有特別高的靈敏度。 PMT也有許多其他優點,如高響應速度。由於小柴昌俊教授使用光電倍增管來探測微中子於2002年獲頒 貝爾物理學獎,光電倍增管在近期間受到廣泛的注意。近期PMT的應用在很多需要高精度光學量測領域不斷的在成長。在醫療領域中,光電倍增管被用在臨床檢查設備以及核子醫學影像和診斷系統。在涉及化學分析領域,光電倍增管被用在各種類型的分析儀器包括分光光度計,環境測量設備,等等。在學術研究領域中,光電倍增管被運用在高能物理實驗。在測量和工業領域中,光電倍增管被運用在如油井探勘和輻射測量;在光學領域中被運用在雷射掃描式共焦顯微鏡(LSCM)。 在半導體領域光電倍增管也被廣泛使用在晶片表面檢查,電漿製程監控,和厚度測量。

In the photosensor field, Hamamatsu Photonics photomultiplier tubes (or PMT) are known to have particularly high sensitivity. Hamamatsu PMT also have dozens of other advantages such as high-speed response time. Hamamatsu Photinics PMT are the subject of recent wide attention because of their use to detect neutrinos by Professor M. Koshiba who received the Nobel Prize in Physics in October 2002. Currently, PMT use is growing in a diverse range of fields where highly precise photometric capabilities are required. In the medical field, the PMT is used in clinical examination equipment as well as nuclear medical imaging and diagnostic systems. In fields involving chemical analysis, the PMT is used in various types of analytical instruments including spectrophotometers, environmental measurement equipment, etc. In academic research fields, the PMT is used in high energy physics experiments. In the measurement and industry field, the PMT is used, for example, in oil well logging and radiometry; and in the optical field is used for laser scanning confocal microscopy (LSCM). The PMT is also widely used in the semiconductor field for wafer surface inspection, plasma process monitoring, and thickness measurement.

Photomultiplier Tubes And Assemblies For Scintillation Counting & High Energy Physics

Photomultiplier Tubes And Assemblies For Scintillation Counting & High Energy Physics
In radiation measurements, scintillation counters which are combinations of scintillators and photomultiplier tubes are used as most common and useful devices in detecting X-, alpha-, beta-, gamma-rays and other high energy charged particles. A scintillator emits flashes of light in response to input radiations and a photomultiplier tube coupled to a scintillator detects these scintillation lights in a precise way.
In high energy physics experiments, one of important apparatuses is a Cherenkov counter in which photomultiplier tubes detect Cherenkov radiations emitted by high energy charged particles passing through a dielectric material.
To detect radiations accurately, photomultiplier tubes may be required to have high detecting efficiency (QE & energy resolution), wide dynamic range (pulse linearity), good time resolution (T.T.S.), high stablility & reliability, and to be operatable in high magnetic field environment or at high temperature condition. In addition, a ruggedized construction is required according to circumstances. On the other hand, several kinds of position sensitive photomultiplier tubes have been developed and are used in these measurements.
This catalog provides a quick reference for Hamamatsu photomultiplier tubes, especially designed or selected for scintillation counters and Cherenkov radiation detectors, and includes most of types currently available ranging in size from 3/8" through 20" in diameter. It should be noted that this catalog is just a starting point in describing Hamamatsu product line since new types are continuously under-development.

PMT Modules

PMT Modules
People are said to get more than seventy percent of their information about our world from their eyes. However, there are vast sums of information and unknown possibilities hidden within light not visible to the naked eye. This kind of light includes ultraviolet, infrared, X-ray and ultra-low level light impossible for human eyes to detect.
Since its founding Hamamatsu Photonics has for some 60 years been investigating not only light seen by the human eye but also light that far exceeds this level. Hamamatsu Photonics has marketed dozens of products and committed itself to pioneering work in yet unexplored areas in many fields including industrial and academic research. The photomultiplier tube, one typical product from Hamamatsu Photonics is a photodetector offering exceedingly high sensitivity and high-speed response. Hamamatsu has also developed photomultiplier tube modules to make the photomultiplier tube with its amazing history of results, even easier to use in wider applications. This pamphlet serves as your introduction to the photomultiplier tube modules.
