Interactive graphics simulation program for the RF-SQUID

An interactive graphics simulation program for the RF-SQUID (superconducting quantum interference device) has been developed. The program allows the user to graphically observe fluxoid quantization, the amplitude-limiting effect of the tank circuit voltage due to the SQUID coupling, the periodic voltage response due to an external DC flux, the tank circuit and SQUID voltage versus time, and the tank circuit voltage versus current. Having a graphical user interface, the program also provides a means for changing circuit and SQUID parameters, namely, RF drive, DC bias, coupling, tuning, Q, and critical current.<
