A later phase of the Atrap experiments will use a superconducting solenoidal
magnet with several metal coils spiraling the magnet in an array of complicated patterns, and a clear plastic sheet with photomultipliers surrounding it.
According to the Helmholtz' theorem, we can decompose the current density (or any vector field) into a solenoidal
(transverse) part [J.
i) the magnet assembly including the solenoidal
and dipole coils, the supporting former structure, the thermal shields and cryogen chambers as needed, the cryostat, the top and bottom flanges supporting (respectively) the gyrotron tube and the gyrotron oil tank, the openings for vacuum pumping, measurement and safety valves, and the current leads and electrical connections.
2] of the torus diminishes and its solenoidal
inductance is ~ [b.
Biasing of an inner core relative to the outer wall produces a radial electric field which will drive supersonic azimuthal rotation and the resulting centrifugal force will contain plasma to the solenoidal
The niobium-titanium solenoidal
magnet is contained in an annular dewar bottle containing liquid helium.
This condition requires that the vector cDv, having physical dimensions of energy per unit surface, is solenoidal
When the frequency is low, the current J naturally decomposes into a solenoidal
(divergence-free) part and an irrotational (curl-free) part.
Field synthesis in solenoidal
magnetic systems (review)," Instruments and Experimental Techniques, No.
Solar cells and solenoidal
magnet coils would create a dense, magnetized plasma that would generate an electromagnetic field 10 miles to 12 miles in radius around the spacecraft.
r]) correspond to solenoidal
parts (loop basis functions) and non-solenoidal
parts (star basis functions), respectively.
In this study, the problem amenable to analytic solution given below will be solved subject to the initial solenoidal
