A synchrotron method and apparatus that reduces or eliminates the need for quadrupole focusing elements by using a flattened magnetic coil system to minimize the space between bending magnets, along with a negative ion beam source and tandem accelerator, allowing for a more compact design with tightly controlled proton beams and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If quadrupole focusing elements are used in the synchrotron accelerator, then beam focusing is improved, but the device size and power consumption increase significantly
Solution Approach 1:
The patent removes quadrupole focusing elements from the synchrotron accelerator system entirely, extracting the problematic component that caused size and power consumption issues while maintaining beam focusing through alternative means
Solution Approach 2:
The bending magnets in this invention serve multiple functions: they provide beam bending/steering and simultaneously provide focusing effects, eliminating the need for separate quadrupole focusing elements and reducing overall system complexity and size

AI summary
The invention comprises a flattened magnet coil system that reduces space between a first magnet turning section and a second magnet turning section in a synchrotron accelerator, which reduces or eliminates need for one or more quadrupole focusing elements in the accelerator. Optionally, a coil, in the flattened magnetic coil system, is wrapped about a central metal member between yoke members of a magnet. The coil has a first width and a first thickness along the length of the magnet and a second width and a second thickness along the end of the magnet where the first width is larger than the second width and the second thickness is larger than the first thickness allowing a smaller distance between the first magnet turning section and the second magnet turning section while maintaining current flow in the coil.
