My professor has given me a project, figure out how to magnetically shield some detectors which surround a solenoid. Now, we have mumetal tubs which fit the detectors, but he wants numbers. The solenoid outputs a maximum of 6 Tesla, and it's in a dewer, so there's no way for me to perform actual data measurements. He told me to perform a simulation, given the solenoid's dimensions. The problem is, I'm not sure where to start. He told me, at the beginning of this project, that he's "ignorant in this area" and that I have to find it out myself, including the resources. I have yet to take Intermediate E&M yet, so I'm sort of at a loss at the magnetostatics of this all. I have some resources on magnetiostatics, but I was wondering if any of you had any good resources on magnetic shielding, possibly even on modeling it in something like MATLAB or something? I can't really find anything. I got a book, Applied Electromagnetics using Quickfield and MATLAB, by Claycomb, though it doesn't really talk about how to model it, or even how this magnetic shielding occurs. Am I trying to find an answer to something that is above my level, and that I probably won't understand until grad school? Thanks in advanced. Edit: My professor is in Nuclear Physics. I have asked people in the High Energy Department, hoping that they would have some information, as they would deal with stuff like that at places like CERN and the like, but they couldn't help either and didn't have any references for it. All I was able to ascertain from a professor is that "common practice" is to put the PMT 1 mumetal tube diameter inside the tube.
