Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies face challenges in measuring the spin dependence of nuclear transmutation processes, particularly at kinetic energies ranging from hundreds of keV to several MeV, due to limitations in particle range and space charge effects in matter.
Innovation Solution
The proposed solution involves a predominantly electric E&M storage ring with superimposed magnetic bending, allowing for the co-circulation of two different particle type beams at different velocities. This configuration enables 'rear-end' collisions, where faster bunches pass through slower bunches, facilitating the study of spin dependence in nuclear scattering.

Engineering Contradiction Analysis
1Measurement precision
If conventional particle accelerators are used to study nuclear transmutation, then kinetic energies can be achieved, but particle range and space charge effects limit measurement precision
Solution Approach 1:
The patent replaces conventional magnetic storage rings with an electromagnetic (E&M) storage ring system that uses electric fields primarily for beam confinement and steering. This substitution reduces the mechanical complexity of magnetic field generation and allows for more precise control of particle trajectories, thereby improving measurement precision while minimizing space charge effects through optimized field configurations.
Solution Approach 2:
The invention changes the fundamental parameters of the storage ring by using predominantly electric fields instead of magnetic fields for beam control. This parameter change allows for different operational characteristics including reduced space charge effects and improved ability to measure spin dependence at specific kinetic energy ranges, directly addressing the measurement precision limitation.
2Duration of action of moving object
If magnetic storage rings are used for beam circulation, then beams can be stored, but device complexity increases due to multiple deflection units
Solution Approach 1:
The E&M storage ring design integrates multiple functions into a unified system where electric and magnetic fields work together in a coordinated manner. The electric fields handle primary beam confinement and steering while magnetic fields provide supplementary control, creating a multi-functional system that reduces overall device complexity compared to purely magnetic systems while maintaining extended beam storage capability.
Solution Approach 2:
By substituting magnetic field-dominated systems with electric field-dominated E&M storage rings, the patent simplifies the deflection units configuration. Electric fields can be more easily generated and controlled using electrostatic plates, reducing the complexity of magnetic pole arrangements and field generation mechanisms while maintaining beam storage duration.
3Productivity
If high kinetic energies are used for nuclear collisions, then reaction rates improve, but center of mass energy control becomes difficult
Solution Approach 1:
The E&M storage ring system enables independent control of beam energies and collision parameters through variable electric and magnetic field configurations. This allows the system to maintain high reaction rates by keeping beams at high kinetic energies while simultaneously achieving precise center of mass energy control through field parameter adjustment, resolving the contradiction between productivity and measurement precision.
Solution Approach 2:
The invention implements dynamic control of field parameters during beam circulation and collision events. By continuously adjusting electric and magnetic field strengths and configurations, the system can optimize both reaction rates and center of mass energy precision in real-time, allowing high productivity without sacrificing measurement accuracy.
