Jones, good news and bad news. Superconductors do not have zero resistance when not carrying DC. They can not sustain internal electric fields, and AC produces internal fields. Small internal fields destroy cooper pair bonds. This is one reason superconductors can can sustain only limited magnetic fields - because the Hall potential, small as it is, destroys Cooper pairs when the imposed orthogonal magnetic field is large enough. That's the bad news. The good news is that *gaps* between superconductors can be used to generate radiation by imposing a potential across the gap. Unfortunately the gap must be small enough that electrons can tunnel back and forth, because it is this tunneling that occurs in unison that creates the "AC Josephson Effect" that is the subject radiation. A voltage of 10^-6 volts produces radiation at 500x10^6 Hz., so we have 5x10^14 Hz/volt. If you want to create a 1 THz = 1x10^12 Hz, you need to apply (5x10^14 Hz/volt)/(1x10^12 Hz) = 2x10-3 volts or 2 millivolts to the gap. Regards, Horace Heffner
