Radiation Detector Segmented Resistor Chains for Output Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radiation detectors with multiple segments face challenges in reducing the number of outputs while maintaining good segment discrimination characteristics, often degrading performance when trying to minimize outputs.
Innovation Solution
The radiation detector employs a configuration with multiple radiation detection units, each comprising a first and second scintillator portion optically coupled in a specific direction, connected to separate resistor chains for light detection, allowing outputs from both ends of each chain to be used for segment discrimination, thereby reducing the number of outputs while maintaining effective discrimination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If all light detection portions are connected to a single resistor chain to reduce outputs, then the number of outputs is reduced, but the discrimination characteristic between segments is degraded
Solution Approach 1:
The light detection portions are divided into two groups connected to separate resistor chains (first resistor chain and second resistor chain). This segmentation allows the system to reduce the number of outputs while maintaining discrimination capability by processing outputs from both chains together to identify the specific segment where scintillation light is generated.
2Measurement precision
If the number of segments to be discriminated is increased, then the discrimination capability is enhanced, but the number of outputs required increases
Solution Approach 1:
Outputs from both the first resistor chain and the second resistor chain are combined and processed together to specify the segment where scintillation light is generated. This merging approach allows the system to discriminate between multiple segments using a reduced number of outputs, as the combined information from both chains provides sufficient discrimination capability.
