Cornell ERL FFAG Magnet Design
Explore the magnet design for Cornell's Energy Recovery Linac Fixed-Field Alternating Gradient (ERL FFAG) by Wuzheng Meng using Dejan's lattice. Details of the quadrupole focusing and combined function magnet for defocusing are provided, along with the current status of the project. Feedback is needed from vacuum chamber designs to further adjust the gap and aperture for optimal performance. Check out the images for a visual representation of the design elements.
