WISCONSIN ATOM SMASHER
Electricity - High-frequency Voltage
June 20, 1936
Looking down the twenty-foot long chamber which houses the new University of Wisconsin apparatus for accelerating atom particles in research on cracking atomic nuclei.
Potential energy of 2,500,000 electron-volts will be developed by the device.
This photograph shows a 600,000-volt electric spark jumping from
the inner accelerator to the outer metal shield.
