Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of scintillator panels with photo-detection substrates requires multiple steps and can cause damage to the scintillator panels during handling and bonding, leading to inefficiencies and potential damage.
Innovation Solution
The scintillator panel is designed with a substrate and scintillator layer having a non-perpendicular angle, allowing for easy cutting and molding into arbitrary shapes, and incorporating a barrier layer to protect the scintillator layer from moisture and impact, with a protective film enhancing adhesion and reducing air bubble accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the scintillator panel is molded to have a predetermined shape and then bonded to a photo-detection substrate, then the radiation detector can be manufactured, but multiple steps of work are required and damage to the scintillator panel during assembly work occurs
Solution Approach 1:
The substrate and scintillator layer are combined into a single integrated scintillator panel structure, where the substrate serves both as a structural base and as part of the bonding interface. This integration eliminates separate handling of the scintillator layer, reducing damage risk during assembly while maintaining manufacturing feasibility.
Solution Approach 2:
The scintillator panel is pre-formed with the substrate and scintillator layer integrated before assembly with the photo-detection substrate. This preliminary integration of critical components reduces the number of subsequent handling steps and minimizes exposure to damage during the assembly process.
2Adaptability or versatility
If the scintillator layer is cut using a paper cutter to obtain a desired shape, then the scintillator panel can be formed, but the scintillator layer is vulnerable to impact damage
Solution Approach 1:
The substrate provides localized structural support and protection to the scintillator layer, particularly at the boundaries and cut edges where vulnerability to impact is highest. The substrate acts as a protective frame that maintains the integrity of the scintillator layer while allowing shape customization.

AI summary
A scintillator panel 10 includes a substrate 11 having a substrate main surface 11a, a substrate rear surface 11b, and a substrate side surface 11c; and a scintillator layer 12 having a scintillator rear surface 12b formed of a plurality of columnar crystals, a scintillator main surface 12a, and a scintillator side surface 12c. The substrate side surface 11c and the scintillator side surface 12c are substantially flush with each other. In the substrate 11, an angle A1 between the substrate rear surface 11b and the substrate side surface 11c is smaller than 90 degrees.
