Processing steps

Step	Chronology	Date	Type	Process	Changes
#1	before layer formation	2012-04-06	mechanical	grinding	bulk meteorite reduced to grains with size lower than 10 microns
#2	before layer formation	2012-04-06	thermal	300 mg of commercial ultrapure KBr powder was heated under ambient air to 80°C overnight (~10h)	removal of adsorbed/hydration water in KBr powder
#3	before layer formation	2012-04-06	mixing	homogeneous mixing	1.0 mg of grinded meteorite was weighed and mixed with 300 mg of dried commercial ultrapure KBr powder
#4	before layer formation	2012-04-06	pressure	pressure	formation of a pellet of 13mm diameter and 0.8 mm thick under 400 bar of pressure
