%X We report an investigation concerning Helium pressure effect on the formation of nanotubes in arc discharge cathodic deposits by thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). Compared with the same thermal analysis of C60/70 and graphite, the results show that the ratio of the nanotubes to nanoparticles in deposits increases with increasing helium pressure ranging from 10.6~93.3kPa. These results can be probably regarded as an approach for controlling the ratio by controlling hclium atmosphere conditions.
