An Underappreciated Radiation Hazard from High Voltage Electrodes in Vacuum
The use of high voltage (HV) electrodes in vacuum is commonplace in physics laboratories. In such systems, it has long been known that electron emission from an HV cathode can lead to bremsstrahlung X-rays; indeed, this is the basic principle behind the ...
