Mass

Substrate material
pressed PEG powder
Substrate comments
The substrate is formed by powdered polyethylene glycol (PEG) (with an average molecular mass of 8000 g/mol, from Fisher Scientific) that has been pre-pressed into a pellet (20 mm in diameter.
Comments
The pellet was prepared by pressing (7 tons for 5 min) ~240 mg of the powedered material (grain size 1–100 µm) on top of a PEG substrate pellet. The PEG layer is used as a substrate to avoid pellet break. The sample layer is thick enough (> 500 µm) to avoid any ion or photon from interacting with the substrate during the experiment.
