I have been asked to help out with an experiment at the Advanced Photon Source here in the US. As I understand it, there will be several experiments taking place several weeks apart from one another. I will be up there for only about 4-5 days each time. There is even a possibility (though I'm not holding my breath) that I may be able to get my name on a paper. Needless-to-say, I'm really excited (and grateful) to have been given such an opportunity, but, given that I'm currently only taking freshman-level math/science courses, I'm a little worried. I guess my question is: how much help can I really be? What can I expect? Thanks in advance.
