( Brand: Hamamatsu ), ( Part Type: Module )
The Hamamatsu H7828 Photomultiplier Module is a high-performance, versatile photon detection device designed for a wide range of applications in the scientific and industrial sectors. This photomultiplier tube (PMT) offers exceptional sensitivity and speed, making it an ideal choice for applications requiring rapid and precise photon detection, such as particle physics, spectroscopy, and astronomy.
The H7828 is a R7600-type PMT, featuring a large 23.8 mm diameter photocathode made of bialkali S20 photocathode material. This photocathode provides excellent quantum efficiency, with a maximum of 20% at 550 nm, allowing the module to detect a broad spectrum of photons. The photocathode's large size also increases the PMT's light-collecting area, resulting in increased sensitivity and improved signal-to-noise ratio.
The H7828 is equipped with a 9-stage dynode chain, providing a gain of up to 106. This high gain allows the PMT to detect single photons with high efficiency, making it suitable for applications requiring low-level light detection, such as single-photon counting or high-resolution spectroscopy. The dynode chain is designed to minimize afterpulsing, reducing the likelihood of false signals and improving the PMT's overall performance.
The Hamamatsu H7828 Photomultiplier Module features a base-biased operation mode, which simplifies its installation and reduces the need for external power supplies. The module also offers excellent energy resolution, with a full width at half maximum (FWHM) of 130 eV at 5.5 keV, ensuring accurate and precise measurements in energy-discriminating applications.
The H7828 is housed in a compact and robust 35 mm diameter aluminum housing, with a 20 mm diameter optical entrance window. The module is compatible with various mounting options, including 25 mm and 36 mm diameter flanges, allowing for easy integration into a variety of experimental setups.
In summary, the Hamamatsu H7828 Photomultiplier Module offers exceptional sensitivity, speed, and energy resolution, making it an excellent choice for applications requiring precise and rapid photon detection. Its large photocathode, high gain, and base-biased operation make it versatile and easy to use, while its compact and robust design ensures reliable performance in a wide range of environments.
