In this picture I am sitting in the door of the
Cockroft-Walton Accelerator at Fermilab.
This is where the protons at Fermilab
start. This little room contains a
bottle of hydrogen (which is an electron and a proton).
From here, the protons are
accelerated through a
series of machines. When they reach high energies, the protons
are used to make
particle beams for MiniBooNE
and the other
