A facility for synthesizing fullerenes by evaporating graphite at a lo
w helium pressure in an are discharge with a power of similar to 30 kW
and a current of similar to 1000 A is described. The content of C-60/
C-70 fullerenes in the resulting soot is about 15%. The process can be
investigated and the optimal parameters can be determined by tuning t
he synthesis parameters over a wide range.
