Meissner Effect- magnetic focusing

Click For Summary
SUMMARY

The discussion centers on the application of superconductors, specifically superconducting cylinders, in enhancing magnetic field focusing for Gauss guns. Participants confirm that superconductors can function as "flux focusers," typically utilizing thin films rather than cylindrical forms. The proposed design, while innovative, is deemed inefficient compared to traditional Gauss gun configurations that employ a series of electromagnets for optimal acceleration. The idea of using a hollow cylinder to extend the magnetic field in one direction is presented as a potential solution to simplify coil activation.

Could superconductors be used to focus a magnetic field? For instance, let's say we have a superconducting cylinder and we place a wire coil in one end. If we put current through the wire, could it be used as a more effective Gauss gun than the same coil without the superconducting cylinder?

Well, you can (and people do) use superconductors as "flux focusers", although that term usually refers to a thin superconducting film, not a cylinder.

However, I don't think the design you are proposing would be very efficient; AFAK Gauss guns are usually designed to us a ROW of electromagnets that gradually accelerate the slug; I can't see how a flux focuser would help.
 
It would be a hollow cylinder. My idea was to use cylinder to extend the coil's magnetic field over a large distance in one direction. That way you wouldn't have to deal with the hassle of switching the coils on and off at the right times.
