EIC Magnets: Work in Progress

Work in progress on EIC magnet designs from Ramesh Gupta (a large amount of work is being done by others also).
WARNING: Please note that the individual presentations below may be out of date from the current design, and may even contain errors. These are the slides shown during the working meetings.
The purpose here is to record how the designs have evolved, why certain choices were made at that time, and what options were evaluated. These presentations should also be useful to become familiar with some (limited to my work only) of the EIC IR superconducting cable magnet design work quickly (please also visit: EIC Tutorials and Magnet Design Help).
