Solution Overview
Problem
Existing gas detectors for elementary particles face manufacturing complexity and sensitivity differences among conductive strips, which complicate the detection of multiple impact points and require additional compensation mechanisms.
Innovation Solution
A gas detector design where all conductive tiles are fabricated simultaneously on the same front face of the dielectric layer, with identical surface areas and distances from the outer face, eliminating the need for sensitivity compensation and simplifying the manufacturing process, and using a resistive layer to distribute avalanche charges over a larger surface for improved spatial resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conductive strips are made on different levels of depth in the dielectric layer to achieve electrical insulation while crossing, then spatial resolution and ability to determine multiple impact points is improved, but manufacturing complexity increases
Solution Approach 1:
The patent transitions from a three-dimensional arrangement (conductive strips at different depths) to a two-dimensional arrangement (conductive strips on the same plane). This is achieved by using conductive tiles that are all located on the same front face of the dielectric layer, eliminating the need for multi-level fabrication while maintaining the ability to determine multiple impact points through the periodic paving pattern and charge distribution analysis
2Measurement precision
If conductive strips are made on different levels of depth, then the ability to determine multiple simultaneous impact points is improved, but sensitivity differences among strips require compensation mechanisms
Solution Approach 1:
The patent applies equipotentiality by ensuring all conductive tiles are located at the same distance from the outer face of the dielectric layer. This creates uniform electrical conditions for all tiles, eliminating sensitivity differences that would otherwise require compensation mechanisms. The periodic paving pattern ensures that all tiles have identical geometric and electrical properties relative to the gas chamber
Solution Approach 2:
The patent achieves homogeneity by making all conductive tiles identical in size, shape, and position relative to the outer face. This uniformity ensures that all tiles have the same sensitivity characteristics, allowing direct comparison of charge measurements without requiring sensitivity matching or compensation for positional variations
3Measurement precision
If individual conductive pads are used instead of conductive strips, then spatial resolution is improved, but the number of sensor inputs required increases significantly
Solution Approach 1:
The patent merges the functionality of multiple individual conductive pads into fewer conductive tiles arranged in a periodic paving pattern. By connecting adjacent tiles of the same color, the system maintains the spatial resolution benefits of fine-grained segmentation while reducing the number of independent sensor inputs through signal integration across multiple tiles
