  A Multi-dipole line cusp configured Plasma Device (MPD) having six
electromagnets with embedded Vacoflux-50 as a core material and a hot
filament-based cathode for Argon plasma production has been characterized by
changing the pole magnetic field values. For the next step ahead, a new
tungsten ionizer plasma source for contact ionization cesium plasma has been
designed, fabricated, and constructed and thus plasma produced will be confined
in MPD. An electron bombardment heating scheme at high voltage is adopted for
heating of 6.5cm diameter tungsten plate. This article describes the detailed
analysis of the design, fabrication, operation, and characterization of
temperature distribution over the tungsten hot plate using the Infrared camera
of the tungsten ionizer. The tungsten plate has sufficient temperature for the
production of Cesium ions/plasma.
