That's right!  Now that you mention it, I saw the actual first accelerator.
It is now on display, of all places, at the Science Museum in London.  I may
have taken a picture of it when I was there last fall.  The accelerator has
been turned into a display and parts of it have been cut away to show the
inner structure.  I do remember seeing the concentric aluminum shells,
although I believe they were oblong as opposed to spherical.  I'll see if I
can find the photo.

Thanks for bringing this up.
