Modern warfare has made impressive strides in the past century, especially in the areas of communications, RADAR and surveillance. On the opposite side of the coin are the military SIGINT (SIGnal INTelligence) systems which attempt to detect, copy, j

The primary voltage standard system based on the Josephson junction array (JJA) produces the ultimate in accuracy for dc voltage calibration. However, it is only used in the highest level standards laboratories due to the expense and inconvenience of

Permanent magnet structures based on magic spheres and magic toroids afford the possibility of synchrotron and wiggler radiation sources in which the electrons describe circular mean paths rather than the usual rectilinear ones. We analyze toroidal s

The mass and bulk of the magnetic focusing structures of traveling wave tubes depend greatly on the details of their design. The authors describe several permanent magnet structures that use no iron pole-pieces and depend upon magnetically rigid perm
