Solution Overview
Problem
Existing neutron detection arrays in negative pressure environments face inefficiencies due to air scattering and attenuation, which can lead to erroneous detection and increased costs from numerous vacuum seals, and potential seal malfunctions.
Innovation Solution
The design includes a multi-chambered atomic particle detection assembly with a junction apparatus maintaining a pressure difference between chambers, using a combination of seals and a support member to minimize the number of vacuum seals required, allowing for efficient neutron detection while maintaining a pre-determined pressure differential.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If PSDs operate in a negative pressure environment to reduce air scattering and attenuation, then detection accuracy is improved, but the number of vacuum seals required increases
Solution Approach 1:
The detection array is divided into multiple independent modular assemblies, each containing its own vacuum chamber and seal configuration. This segmentation allows each module to be independently sealed and tested, reducing the overall complexity of the vacuum system while maintaining the negative pressure environment needed for accurate neutron detection.
Solution Approach 2:
The patent implements a nested chamber structure where an inner vacuum chamber is positioned within an outer chamber. The inner chamber contains the PSD and is sealed independently, while the outer chamber provides additional structural support and housing. This nested configuration allows the vacuum environment to be maintained with fewer seals compared to a fully segmented approach.
2Productivity
If the number of PSDs is increased to improve detection efficiency, then detection effectiveness is improved, but fabrication and installation costs increase
Solution Approach 1:
The detection array is divided into multiple identical modular assemblies that can be manufactured using standardized processes. Each module contains a specific number of PSDs arranged in a compact configuration, allowing for economies of scale in manufacturing while maintaining high detection efficiency through the combined array of multiple modules.
Solution Approach 2:
Multiple PSDs are integrated into a single modular assembly with shared structural components, electrical connections, and vacuum sealing systems. This merging reduces the total number of individual components needed compared to separate assemblies for each detector, thereby reducing fabrication and installation costs while maintaining high detection efficiency.
3Measurement precision
If the number of vacuum seals is increased to maintain negative pressure environment, then seal reliability is worsened, but detection accuracy is maintained
Solution Approach 1:
The vacuum system is segmented into multiple independent chambers, each with its own seal configuration. This allows for localized vacuum maintenance where only the specific chamber experiencing issues needs to be resealed or replaced, rather than requiring system-wide vacuum restoration, thereby improving overall system reliability while maintaining detection accuracy.
Solution Approach 2:
The modular design includes redundant seal configurations and backup vacuum chambers that can be quickly swapped in case of seal failure. This beforehand preparation ensures that detection accuracy is maintained with minimal interruption, as failed modules can be replaced without affecting the entire array's vacuum environment or detection capabilities.

AI summary
An atomic particle detection assembly includes at least one atomic particle detector positioned within a first chamber having a first operating pressure. The assembly also includes at least one junction apparatus coupled to the at least one atomic particle detector. The at least one junction apparatus includes at least one wall that at least partially defines a second chamber having a second operating pressure. The second pressure is greater than the first pressure and the at least one junction apparatus facilitates maintaining a predetermined pressure difference between the first chamber and the second chamber.
