Charged Particle Source Unit Replacement Through a Side-Wall Chamber Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charged particle sources in systems like transmission electron microscopes need to be easily replaceable due to service life limitations, but existing methods often require high-altitude work and pose safety risks.
Innovation Solution
A charged particle beam system with a chamber, a detachable charged particle source unit, and a side-wall chamber door allows for easy replacement by opening the door, removing the old unit, and introducing a new one through the door, using a supporting member for attachment.

Engineering Contradiction Analysis
1Duration of action of stationary object
If the charged particle source is made replaceable, then the service life and maintenance flexibility are improved, but the device complexity and safety risks increase
Solution Approach 1:
The charged particle source is separated into a modular unit that can be independently removed and replaced. The source unit includes the charged particle source, supporting member, and electrical connection components as integrated segments that can be handled as a single replaceable module, simplifying the replacement process while extending service life.
Solution Approach 2:
A supporting member acts as an intermediary component between the charged particle source and the chamber wall. This supporting member includes electrical connection components and provides a standardized interface for attachment and detachment, reducing the complexity of direct connections while enabling safe replacement operations.
2Ease of operation
If the chamber door is provided for access, then the ease of operation and safety are improved, but the device complexity increases
Solution Approach 1:
The chamber door is extracted as a separate access component from the main chamber structure. The door is specifically positioned to provide access to the charged particle source region, allowing operators to open only the necessary portion of the system for replacement operations, improving ease of operation while minimizing the impact on overall chamber integrity.
Solution Approach 2:
Access to the charged particle source is provided through a side-wall chamber door rather than requiring top-down access. This dimensional change in access approach allows replacement operations to be performed at a more convenient height and position, improving operational safety and ease without significantly increasing structural complexity.
3Ease of repair
If the supporting member is detachable, then the ease of repair and replacement are improved, but the reliability of electrical connection may worsen
Solution Approach 1:
The supporting member includes pre-configured electrical connection components (such as contact points, conductors, or connectors) that are prepared in advance for reliable attachment. These connection elements are positioned and structured to ensure proper electrical contact is established before the charged particle source unit is fully installed, maintaining connection reliability while enabling easy replacement.
Solution Approach 2:
The electrical connection system incorporates conductive materials or conductive coatings on the supporting member and charged particle source interface. This substitution of mechanical contact with optimized conductive pathways ensures reliable electrical connection during detachable operations, maintaining performance while enabling ease of repair and replacement.
