Sweep Magnet #1 (primary sweeping magnet collimator cave)
The primary sweeping magnet in the collimator cave is a FNAL PDV permanent magnet dipole. The documentation which we received long ago can be found at the following links.
The PDV magnet is constructed of magnetized ferrite plates, The cross section of the magnet is shown below.
We have a few pictures of the PDV magnets which we have in storage.
