				The magnetic flux quantum Φ0 is the quantum of magnetic flux passing
				through a superconductor. The inverse of the flux quantum, 1/Φ0,
				is called the Josephson constant, and is denoted KJ. It is the
				constant of proportionality of the Josephson effect,  relating the potential
				difference across a Josephson junction to the frequency  of the irradiation.
