The HeatWave generator includes provision for external interlocks to remove gyrotron beam voltage.

The purpose of the external interlocks is to ensure that the user’s system safety interlock turns off the

generator if a hazardous situation arises. Hardwired shutdown logic sends a command to turn off the RF

in a few tens of milliseconds after receiving the command.
