( Brand: Emi ), ( Manufacturer Part Number: 9791KB ), ( Part Type: Tube ), ( Country/region Of Manufacture: United Kingdom )
The 9791KB EMI Photomultiplier Tube (PMT) is a high-performance optical detection device, specifically designed for use in various scientific and industrial applications. This particular model measures 130mm in diameter, making it a suitable choice for applications requiring a moderate-sized PMT.
The PMT is a bialkali type, which means it uses a mixture of two alkaline earth materials as the photocathode material. This combination provides excellent photon detection efficiency over a wide range of wavelengths, from the ultraviolet to the near-infrared spectrum. The specific type used in this PMT is SBKCS, a well-known and trusted bialkali photocathode material.
The PMT is also equipped with a CSSB base, which stands for CsSb-coated, Southerns-type bulb with a stainless steel base. This base provides a robust and reliable electrical connection to the PMT, ensuring stable and consistent performance.
The PMT's B14A base further enhances its versatility. This base is compatible with a wide range of high voltage supplies, making it easy to integrate into various experimental setups.
In summary, the 9791KB EMI Photomultiplier Tube is a versatile and high-performance optical detector, suitable for a wide range of applications. Its bialkali photocathode provides excellent spectral sensitivity, while its robust CSSB base and B14A base ensure reliable and stable operation.
Pros of buying a 9791kb EMI Photomultiplier Tube (PMT):1. High Sensitivity: The PMT is known for its high sensitivity, which makes it suitable for low light level applications.
2. Large Photocathode: The 130mm bialkali photocathode provides a large active area, increasing the detection efficiency.
3. Wide Dynamic Range: The PMT has a wide dynamic range, allowing it to handle both low and high photon fluxes.
4. High Operating Voltage: It operates at a high voltage, which can result in a high gain, increasing the signal-to-noise ratio.
5. Robust Design: The PMT is designed to be robust and reliable, with a base made of B14A material, which is known for its stability and durability.
Cons of buying a 9791kb EMI Photomultiplier Tube:1. High Operating Voltage: While the high operating voltage can result in a high gain, it also requires a stable and regulated power supply, which can be expensive and complex to set up.
2. Size and Weight: The large size and weight of the PMT can make it difficult to integrate into certain applications, especially those with space constraints.
3. Cost: The PMT is more expensive than some other types of photomultiplier tubes, due to its high performance and robust design.
4. Requires Cooling: The PMT requires cooling to operate effectively, which can add to the cost and complexity of the system.
Conclusion:The 9791kb EMI Photomultiplier Tube is a high-performance PMT with a large photocathode, high sensitivity, and a wide dynamic range. Its robust design and high operating voltage make it suitable for low light level applications, but its high cost, size, and weight, as well as the requirement for cooling, should be considered before making a purchase.
Recommendation:If the high performance and robust design of the 9791kb EMI Photomultiplier Tube are necessary for your application, and you have the space and budget to accommodate its size and cooling requirements, then this PMT is a good choice. However, if you have less stringent performance requirements or budget constraints, there may be other types of PMTs available that are more suitable for your needs. It's recommended to consult with a technical expert or manufacturer to get the best fit for your specific application.
