Mechanical Design or a 250 Kilogauss Solenoidal Magnet

摘要

The mechanical design and construction of a 5 cm bore, 2 3 cm long solenoidal magnet operated at 250 kilo-gauss is described. The magnet provides confining field for a plasma heated by a CO2 laser. Radial diagnostic ports with a clear aperture of 0.41 cm allow viewing ac¬cess near the magnet midplane. The on-axis field homogeneity is within 5% over a central length of 12 cm. The magnet sustained 500-1000 pulses at the highest field levels before catastrophic failure.
