The advantage of such an arrangement is the!simplicity (tfhere
are no rotating parts), compactness, and tpe possibility df obtaining
Shigh currents directly, 1 which simplifies the power supply of the
S p:•lasma motor. The shortcomings of the arrangpment arc the complexity
of finishing the reactor unit pith a converter, and the&difficulty
involved with studying andadjusting these two fundamential'elements.

Figurc 1.5 shows this type of tw6-circuit unit. The 'irst
circuit consists Qf the reactor 1,.,thcI pump 3, and the thermoelectric
corlyert~er unit 4. Th•,secbnd circuit,,consists of the ?onverter 4,
amid the diaaiator 5'. Each circuit has a compensating compacitor 6'
(shpown here only in th6 radiator circuit). The unit can have one
pump 3 on both circuits, The cooling 6f such aipunp can requireian
additionat cooler-radiator *2.
Whdn the reactor is started there occurs'-heating of the *
