Cold-electron bolometer, as a 1 cm wavelength photon counter

Understand

We investigate theoretically the possibility of using the cold-electron bolometer (CEB) as a counter for 1 cm wavelength (30 GHz) photons.

• To reduce the flux of photons from the environment, which interact with the detector, the bath temperature is assumed to be below 50 mK.
• At such temperatures, the time interval between two subsequent photons of 30 GHz that hit the detector is more than 100 hours, on average, for a frequency window of 1 MHz.
• Such temperatures allow the observation of the physically significant photons produced in rare events, like the axions conversion (or Primakoff conversion) in magnetic field.
