Abstract

This article relates generally to devices for the detection of magnetic flux and more particularly to a superconducting grid for the detection of transient magnetic phenomena. The magnetic field camera disclosed herein permits the digitization of magnetic flux threading a grid at some instant of time by trapping the flux in it in multiples of do and then reading out the flux at a later period of time. The device or camera 1 shown in Fig. 1 consists of a superconducting grid 2 of holes 3 over a ground plane 4. Ground plane 4 or portions thereof can be driven into the normal state. Gates 5 interconnect holes 3. Gates 5 may also be in either the normal or superconducting state.
