Material

class roentgen.absorption.Material(material_str, thickness: Unit("m"), density=None)

Bases: object

An object which provides the properties of a material in x-rays

Parameters:

material_str : str

A string representation of the material which includes an element symbol (e.g. Si), an element name (e.g. Silicon), or the name of a compound (e.g. cdte, mylar). Cap-sensitive.

thickness : astropy.units.Quantity

The thickness of the material in the optical path.

density : astropy.units.Quantity

The density of the material. If None use default values.

Examples

>>> from roentgen.absorption.material import Material
>>> import astropy.units as u
>>> detector = Material('cdte', 500 * u.um)
>>> thermal_blankets = Material('mylar', 0.5 * u.mm)
