Stack

class roentgen.absorption.Stack(materials)

Bases: object

An object which enables the calculation of the x-ray transmission and absorption of a stack of materaials. This object is created automatically when Material objects are added together.

Parameters:

materials (list) – A list of Material objects

Examples

>>> from roentgen.absorption.material import Material, Stack
>>> import astropy.units as u
>>> detector = Stack([Material('Pt', 5 * u.um), Material('cdte', 500 * u.um)])
>>> optical_path = Material('mylar', 50 * u.micron) + Material('Al', 1 * u.mm)

Methods Summary

absorption(energy)	Provides the absorption fraction (0 to 1).
transmission(energy)	Provides the transmission fraction (0 to 1).

Methods Documentation

transmission(energy)

Provides the transmission fraction (0 to 1).

Parameters:

energy (astropy.units.Quantity) – An array of energies in keV

Raises:

ValueError – If energy is outside of the interpolation range of 1 keV to 20 MeV.
