What is difficult about the magnet assembly?

Scratch that. Building traps requires highly controlled magnetic fields
with precisly defined gradients, tunable lasers and stuff like that.
Nothing you can get your hands on easily. And probably not something
you can get working unless someone shows you how to do it.

I wouldnt try to read patents. These are convoluted beasts, written by lawyers
for lawyers. If you want to understand the technology, read the papers. Most
of them are eithe freely available or for a small fee. If you have a good
university nearby you can find them for sure in the physics library.

The trouble with you, Shev, is you don't say anything until you've saved
up a whole truckload of damned heavy brick arguments and then you dump
them all out and never look at the bleeding body mangled beneath the heap
