Light Collection Efficiency for Liquid Scintillation Detecto

AI Thread Summary
To calculate the light yield and light collection efficiency of a liquid scintillation detector, one must consider the geometric efficiency and attenuation of the scintillator material. The formula involves assessing the number of photomultiplier tubes (PMTs) used and their placement relative to the scintillator. If the source is immersed in the scintillator, the geometric efficiency approaches 1, though edge losses may occur unless the scintillator is fully surrounded by PMTs. Accurate calculations require data on the geometry of the scintillator and the configuration of the PMTs. Understanding these factors is crucial for determining the detector's performance.

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.
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
