This presentation is a 3 -minute subset of the entire 15 -minute slide show that runs continuously inside the cut-up magnet display in the Chemistry East hallway next to the E 1 -60 lecture theatre. 2009 Department of Chemistry University of Alberta Edmonton, Alberta Canada

Dissection of a magnet After over 20 years of service, the magnet (its surrounding tanks really) was cut in the Department’s Machine Shop March 2006

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…

…and, finally, the magnet solenoid! February 2007

The last 3 steps side by side The End Thanks for watching!
