Engineering Contradiction Analysis
1Device complexity
If a prior collision reaction cell ion acceleration apparatus with extremely low crosstalk is used, then the apparatus structure is simple, but the transmission efficiency of charged ions is low
Solution Approach 1:
The apparatus is divided into multiple functional modules including a radio frequency quadrupole acceleration module with four electrode sets, a collision reaction cell module with collision chamber and gas injection system, and a detection module. Each module performs a specific function in the ion acceleration and detection process, improving overall transmission efficiency through specialized functional segmentation.
Solution Approach 2:
The apparatus employs dynamic control of electrode potentials and radio frequency fields to optimize ion transmission. The radio frequency quadrupole electrodes dynamically adjust electric fields to guide and accelerate ions, while the collision chamber dynamically introduces collision gas to modify ion trajectories and improve transmission through the apparatus.
2Device complexity
If a prior collision reaction cell ion acceleration apparatus with extremely low crosstalk is used, then the apparatus structure is simple, but the ability to adjust motion trajectory of charged ions is poor
Solution Approach 1:
The radio frequency quadrupole electrodes provide dynamic trajectory control through time-varying electric fields that can steer and focus ion beams. The collision chamber dynamically introduces collision gas at controlled rates to modify ion trajectories through controlled collisions, enabling adaptable trajectory adjustment without increasing overall apparatus complexity.
Solution Approach 2:
The apparatus adjusts trajectory by changing operational parameters including radio frequency field strength and frequency, electrode potentials, and collision gas flow rate. These parameter changes enable flexible control of ion motion trajectories while maintaining a relatively simple apparatus structure.
3Device complexity
If the apparatus cannot change motion trajectory of charged ions well, then the apparatus structure is simple, but the working efficiency is reduced
Solution Approach 1:
The apparatus segments the ion manipulation process into distinct functional zones: the radio frequency quadrupole section for initial acceleration and trajectory control, the collision reaction cell section for trajectory modification through gas collisions, and the detection section. This segmentation enables efficient ion transmission by optimizing each section's function.
Solution Approach 2:
The collision gas introduced in the collision chamber serves as an intermediary medium to modify ion trajectories. By controlling the amount and type of collision gas, the apparatus can efficiently adjust ion paths and improve working efficiency without requiring complex mechanical trajectory adjustment mechanisms.

Function Achieved in This Case
This configuration enhances the transmission efficiency and stability of charged ions by accelerating them through electric fields and allowing them to form new trajectories, improving the overall working efficiency of the apparatus.

AI summary
A collision reaction pool ion acceleration apparatus which has extremely low crosstalk. The apparatus comprises an apparatus body, a vacuum chamber, a first tube bundle channel and a second tube bundle channel. The vacuum chamber is fixedly connected to the interior of the apparatus body; the other end of the interior of the apparatus body is fixedly connected to a first insulation seat. A collision chamber is embeddedly connected to the inside the first insulation seat, and a high-frequency electrode quadrupole lens is fixedly connected to two sides of the collision chamber. When charged ions enter the collision chamber, the high-frequency electrode quadrupole lens focuses on the charged ions, so that the incoming charged ions form a new motion trajectory in the collision chamber, and the charged ions are easily separated from the collision chamber, thereby increasing the working efficiency.
