Making A Transport System

*This project was started by Josefine Metzkes and Alan Stummer in January 2008. Josefine designed the first current scheme, ordered coils and designed the system mounts. Alan took care of all the electronics. Michael Yee then took over from Josefine, integrating the transport system to an experiment that was redesigned in summer 2008, designed and wrapped the "push" coil and mount, and put things together at the end with Dylan. Dylan helped Alan with wiring the electronics.

Details

  • Michael Yee has written has written a couple summary documents:
  • All coils, including the MOT but not the push, were wrapped by Oswald. Oswald has poor customer service, is slow, expensive, but produces good quality coils. However, given our accumulated coil wrapping expertise, we would now choose to spend the time to wrap coils ourselves.
  • Calculations were done using the following mathematica scripts:
  • The transport system mounts were made at the physics dept. machine shop. They are made out of brass, with an insulating plastic layer to inhibit eddy currents. See Josefine Metzkes lab book.
  • Wrapping the push coil required making a jig with a specificed ID and parallel plates a distance apart. LePage 11 epoxy (1 hour cure time) was used to set the coil. Acetate transparencies were used to cover the jig in order to remove the coil once the epoxy had set. Coils were wound in a "double-stack" fashion, starting at the middle of the wire length. See Michael Yee lab book #4.

Final construction (Feb 10-20, 2009)

  • A system mock-up was put in place to determine the "choreography" of water cooliing - which pipes should connect to which, the placement of swage connections, etc.
  • Copper pipe was bent to fit into place on the brass mounts
  • The Copper pie was soldered to the brass mounts
  • Coils were encapsulated with a thermal epoxy (Epoxies Etc resin model # 50-3150 RF with catalyst CAT.150CL13 - has a thermal conductivity of 2 W/mK)
