How to Connect to the Mag-O-Matic2

NOTICE: This webpage and associated files is provided for reference only. This is not a kit site! It is a collection of my work here at the University of Toronto in the Physics department. If you are considering using any schematics, designs, or anything else from here then be warned that you had better know something of what you are about to do. No design is guaranteed in any way, including workable schematic, board layout, HDL code, embedded software, user software, component selection, documentation, webpages, or anything.
All that said, if it says here it works then for me it worked. To make the project work may have involved undocumented additions, changes, deletions, tweaks, tunings, alterations, modifications, adjustments, waving of a wand while wearing a pointy black hat, appeals to electron deities and just plain doing whatever it takes to make the project work.
For use in Joseph's second lab, original contact is Mike Yee, project started July 2007. This project is based on the original Mag-O-Matic, except that A) it has only one channel, B) it is CC rather than just a switch, and D) the MOT coils are permanently in anti-Helmholtz.. The coil driver circuit controls the coils which generate the magnetic fields for the MOT coils. This project is a test bed for constant current (CC) driving of the MOT coils. Current is measured with a hall effect sensor device and compared to a set value. Normally this would be mundane but the load is inductive so loop stability depends on control phase shifting. Once this system is worked out, it will be repeated several times for the transfer coil setup as part of the larger lattice experiment.Basic Mag-O-Matic2 parameters include:
