Randy Benson in full action First cut of the seemingly endless layers of Mylar foil Mylar reduces heat radiation - just like an outdoor emergency blanket …more Mylar cutting… …after the Mylar… another tank… …and back to more Mylar… 3 layers of various metals 2 layers of Mylar …and still no magnet in sight! Getting closer - at least it starts to look magnet-like A magnet wrapped in hockey tape? Careful peek behind the tape - this is not the magnet (yet)! Next up: cryoshim coils purpose: improve the homogeneity of the magnet Behind the cryo-shims another metal container… the magnet solenoid! February 2007 finally, …and, The last 3 steps side by side The End Thanks for watching! Acknowledgments magnet cutting RANDY BENSON display case design build PAUL CROTHERS photography DEPT.
