Light Collection Efficiency for Liquid Scintillation Detecto

Click For Summary
SUMMARY

The calculation of light yield and light collection efficiency in liquid scintillation detectors involves understanding geometric efficiency and attenuation within the scintillator material. Key factors include the number of photomultiplier tubes (PMTs) used, the geometry of the scintillator, and the positioning of the PMTs. When the source is immersed in the scintillator, the geometric efficiency approaches 1, although edge losses may occur if the scintillator is not fully surrounded by PMTs. Accurate calculations require specific data regarding these parameters.

How do I calculate the light yield and light collection efficiency of a liquid scintillation detector? Couls someone give me a formula for that? What data do I need to calculate it?

THanks a bunch!

How many photomultiplier tubes is one using. What is the geometry of the scintillator and the location of the PM tube or tubes?

One has to look at the geometric efficiency and the attenuation within the scintillator material.

For the system, one has to consider the geometric efficiency of the source with respect to the scintillator. If the source is immersed/dissolved within the scintillator, the geometric efficiency is close to 1, but there will be some edge losses, unless the scintillator is completely surrounded by PM detectors.
