I might just mention that Luis Alvarez also invented and built a linear accelerator for 32 MeV protons, and this is the scribbling on their blackboard when they first got a beam in 1947.
|Search for the first beam from the proton linear accelerator (10/16/47). Alvarez's 8:30 p.m. blackboard calculation 'proving' that geometry must be changed and that the "machine would not work", with an added note that at 2:40 a.m., six hours later, they achieved the beam.|
