  In our work we are focused on study of powder formation in C2H2/Ar plasmas.
In this scope we used a combination of FTIR and mass spectroscopy, which are
the mostly used experimental techniques for plasma powder formation
diagnostics. To test the proposed mechanism for particle nucleation delay we
measured the particle nucleation under different plasma conditions: firstly we
increased the gas temperature and secondly we changed the background gas from
argon to helium.
