Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation 2011-01-31 fluid physical Co-Injection in the PAMPRE chamber of 5.5 sccm of $N_2$:$CH_4$ gas in a 90%:10% ratio and of 49.5 sccm of pure $N_2$ gas for a total gas flow of 55 sscm + 250ppm pyr
#2 before layer formation 2011-01-31 irradiation irradiation using a RF CCP Plasma at 13.56 MHz and 30 W injected power of the $CH_4$:$N_2$=1%:99% 250ppm pyr gas mixture at ambient temperature and 0.9 mbar formation of tholins grains
#3 before layer formation 2011-01-31 no Collecting tholins grains from the reactor (and thus exposing them to ambient air) No changes observed macroscopically
