Processing steps

Step	Chronology	Date	Type	Process	Changes
#1	before layer formation	2011-01-31	fluid physical	Co-Injection in the PAMPRE chamber of 55 sccm of $N_2$ :pyr$ gas in a 100%:250ppm ratio
#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 $pyr$ : $N_2$ =250ppm:100% 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
