Ok, i want a job that works with particle physics, and somthing to do with the development for Viable Cold or Normal Fusion power Generator and all that where and what can i work as/for
You haven't mentioned your qualifications, so I'll assume that you're just looking into what you'd need. To do actual research in the field, you probably need to have a Ph.D. in fusion physics / nuclear engineering (or a Ph.D. in a closely related field). However, if you want to work in an engineering, or programming, or other support role, the Ph.D. in fusion physics / nuclear engineering is probably not necessary (or desired).
Hopefully, some real fusion scientists weigh in on this (I base this only on my nearly-entirely anecdotal and second-hand hearsay about the operation of such facilities).
