Summary
[edit | edit source]Description |
60-inch cyclotron, circa 1939, showing beam of accelerated ions (perhaps protons or deuterons) escaping the accelerator and ionizing the surrounding air causing a blue glow. (contrast enhanced) This image is a work of the Lawrence Berkely National Laboratory and as such is a work of the US government and therefore in the public domain. |
