Solution Overview
Problem
Neutron detectors face signal degradation and voltage breakdown issues due to long signal transmission distances and reduced pressure in high voltage electronics, which affect the accuracy and reliability of neutron detection.
Innovation Solution
An atomic particle detection assembly with a first chamber maintained at negative pressure for improved neutron transport and detection, and a second chamber at atmospheric pressure housing the sensing electronics to reduce signal degradation and prevent voltage breakdown, utilizing a junction apparatus with a sealing device to maintain different pressures and position sensitive detectors to enhance detection efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sensing electronics are positioned close to the detectors to reduce signal transmission distance, then signal degradation is reduced, but the electronics are exposed to reduced pressure conditions that cause voltage breakdown
Solution Approach 1:
The system is divided into two separate pressure environments: the detectors operate in a reduced pressure chamber while the sensing electronics are housed in a separate atmospheric pressure chamber. This segmentation allows each component to operate in its optimal pressure condition, resolving the contradiction between signal strength and voltage breakdown prevention.
Solution Approach 2:
A sealed junction apparatus acts as an intermediary between the reduced pressure detector chamber and the atmospheric pressure electronics chamber. This intermediary maintains pressure separation while enabling electrical and mechanical connections, allowing close positioning of electronics to detectors without direct pressure exposure.
2Productivity
If the chamber pressure is reduced below atmospheric pressure to improve neutron transport, then detection efficiency is improved, but voltage breakdown in electronics becomes possible
Solution Approach 1:
The system separates the detection function (requiring reduced pressure) from the electronics function (requiring atmospheric pressure) into distinct chambers. This allows the detection chamber to operate at reduced pressure for improved neutron transport while the electronics chamber maintains atmospheric pressure for stable operation.
