> $120k for a cyclotron is a lot of money, but the fact that a couple of teenagers can even dream of building one is cool. As the article said, this is the price for a build using brand-new parts. The prices of used lab instruments are significantly lower than their list prices, a 10x or even 100x reduction is not unheard of. So, at least its electronic instrumentation is going to be cheaper. Though, I know nothing about the mechanical, vacuum, or magnetic part.
