Resonance degenerate plane lattice of magnetodielectric spheres with a hole
The solution of the problem on electromagnetic waves scattering by a plane lattice of magnetodielectric spheres, in which the lattice degenerate resonance is excited, is considered.
Structural Functions of Electromagnetic Coupling of the Magnetodielectric Sphere Resonance Grating
Drawing of structure functions of electromagnetic coupling of magnetodielectric sphere electric and magnetic resonance plane gratings is considered
Long Ceramic Beam Tubes for Accelerator Magnets
The ceramic beam tubes for the fast and abort kickers and the bucker and pinger magnets used at Fermilab must meet a number of exacting requirements. The tubes must be long and sufficiently straight so as not to limit magnet design. They must have wall strength capable of withstanding the atmospheric and mechanical forces encountered during construction and operation. Vacuum tight ceramic to stainless steel transitions must be of reasonable cost; they must also withstand high temperature processing and remain vacuum tight to the 10/sup -9/ Torr range. To remove the possibility of static charge buildup each tube must have a surface coating of indium oxide applied to the inner wall. This thin coating is difficult to achieve and requires the most careful attention to detail. The methods used at Fermilab to achieve these goals are presented in this paper.
