Abstract:
The field configuration formed by the superposition of a cusped
magnetic field and an electrostatic octapole field provides a closed system of confinement for a charged particle. In a cusped magnetic
field, the Störmer region which constrains a charged particle is open, but it is closed by adding a potential barrier made by the
octapole field. One-component plasmas are thus expected to be confined in this configuration, preserving superior characteristics
of the cusp field for plasma stability. A preliminary experiment was performed on the confinement of electrons in this field configuration. An electron plasma was confined
for 3 s in a magnetic field as weak as B =50 G at the
circular line cusp. The confinement time was roughly proportional to B 2 , suggesting that the confinement would be improved substantially in
a higher magnetic field.
