Description
**9924B Series Photomultiplier Overview** The 9924B series is a cutting-edge photomultiplier tube (PMT) designed for high-performance applications requiring precise light detection and amplification. With a diameter of 29 mm (1.13 inches), this photomultiplier features an end window configuration that enhances its sensitivity and performance. At the heart of the 9924B is an enhanced green-sensitive bialkali photocathode, which is complemented by a series of 11 high-gain, high-stability SbCs dynodes. These dynodes are crafted in a box and grid design, ensuring optimal functionality and reliability. For applications that demand ultraviolet sensitivity, the 9924QB variant is available. This version is tailored to meet the specific needs of UV-sensitive applications, expanding the versatility of the 9924B series.
The photomultiplier is engineered to deliver high gain and low operating voltage, making it an ideal choice for a wide range of scientific and industrial uses. Its robust construction and design allow for accurate photon counting, especially in bio- and chemi-luminescent sample analysis, as well as in x-ray and gamma-ray spectroscopy. Furthermore, the 9924B series boasts excellent spectral response, with a quantum efficiency that peaks impressively.
It is designed to maintain a low dark current at standard operating conditions, ensuring minimal interference and high precision in measurement. The photomultiplier's construction includes a borosilicate or fused silica window, depending on the model, which contributes to its superior optical clarity and durability. Whether utilized in research laboratories or industrial settings, the 9924B series photomultiplier stands as a testament to advanced photonic engineering, promising reliability and precision in light detection tasks.
