The article mentions that the race venue used to house the world's largest (traditional, HV) electron microscopes at one time. I thought it would be cool if these towers were actually for that but it seems likely the place is just a science museum of sorts now. Or maybe they are some sort of fancy (electrostatic) dust collector?

Oh yes you are right!

That's apparently part of the first 1MeV TEM. Should be the high voltage source for the electron gun. The electron optics were most likely magnetic, not electrostatic.

There is a whole movie about it:

Later MeV TEMs looked very different, and are now replaced by aberration corrected tools...
