3.3.27 Material table

There is a set of predefined materials for use in elements such as collimators, e.g.

“Air” “LiquidHelium”
“Aluminium” “NbTi”
“BeamGasPlugMat” “Niobium”
“Beryllium” “Silicon”
“CarbonMonoxide” “SmCo”
“CarbonSteel” “Soil”
“Concrete” “Titanium”
“Copper” “TitaniumAlloy”
“Graphite” “Tungsten”
“Invar” “Vacuum”
“Iron” “Vanadium”
“LaserVac” “Water”
“Lead” “WeightIron”
“LeadTungstate”

Currently “Air”, “CarbonMonoxide” and “Vacuum” are gas at T=300K, p=10^-12 bar: both “Air” and “Vacuum” are a N(80):O(20) mixture, “CarbonMonoxide is composed of CO molecules.

There are also predefined elements (i.e. atoms) that can be used for building composite materials: "H", "He", "Be", "C" , "N", "O", "Al", "Si", "P" , "S", "Ca", "Ti", “V" , "Mn", "Fe", "Co", "Ni", "Cu", "Nb", "Sm", "W" , "Pb".
