Description
Hydrogen plasmas were produced in an axially symmetric magnetic
field which was nearly uniform in the Lisitano coil
region. The field could be converted from a shallow mirror
to a deep mirror (R = 44), to a cusp geometry by varying
the current ratio in two sets of magnet coils. Unguarded
Langmuir probes and a periodic potential probe proved unsatisfactory
due to sheath growth. A gridded Langmuir probe
measured ion temperature of 26 eV and electron temperature
of 9 eV, with ion density 7 to 10x10^8 cm^-3. The magnetic
boundary value problem was solved analytically and comparison
with previous experiments at Florida Atlantic University
showed the electron temperature to depend on the magnetic
field gradient in the Lisitano coil. It was also seen that
high voltage (250 V) on the periodic probe was not ionizing
neutrals.
