13. 12/02/99Team #12 Optimized Magnet Support EML 4551 Design Selection t Generation of Ideas –Rough Scetches t Concept Screening Matrix –Concept Revisions t Concept Scoring Matrix t Finalized Concept

14. 12/02/99Team #12 Optimized Magnet Support EML 4551 Concepts Generated t Sketches on Overhead t Ideas and Summary –Flat Plate: An outer shell without any marks on the inside surface Fits over existing support like a shell with a small space between the support column and the outer wall for cooling fluid to flow through Fluid flows from top to bottom –Cross-Hatch:  An outer shell with a diamond shaped pattern cut into the inner surface of the shell  Designed to increase the fluid’s flow time by increasing the distance from top to bottom  Fluid flows top to bottom

15. 12/02/99Team #12 Optimized Magnet Support EML 4551 Concepts Generated (cont.) –Rings:  Similar to the insides of resistive magnet  Ring juts out from support column, is used as a cooling fin by drawing heat out from column  Fluid flows from top to bottom, and through holes in fin surface –Dimples:  Similar to the Riveted method.  A flat plate with bumps pressed into the surface  Bumps are pressed into contact with the support column  Bumps are used to increase the travel distance of the fluid  Fluid flows from top to bottom –Riveted:  A flat plate with rivets punched through the plate to the inner side  Rivets are pressed into contact with the support column  Rivets are used to increase the travel distance of the fluid by making the path non-linear  Fluid flows top to bottom
