- class plasmapy.diagnostics.charged_particle_radiography.detector_stacks.Layer(thickness: Unit('m'), energy_axis: Unit('J'), stopping_power: [Unit('J / m'), Unit('m2 J / kg')], mass_density: [Unit('kg / m3'), None] = None, active: bool = True, name: str = '')
A layer in a detector film stack.
The layer could either be an active layer (the actual film medium) or an inum_active layer (a filter or inum_active part of the film, such as a substrate.)
Quantity) – The thickness of the layer, in units convertible to meters.
Quantity) – The energies corresponding to the stopping power array.
Quantity) – The stopping power in the material. Either the linear stopping power (units of J/m) or the mass stopping power (units convertible to J m2 / kg) can be provided. If the mass stopping power is provided, the material_density keyword is required.
Quantity, optional) – The material mass density in units convertible to kg/m3. This keyword is required if the provided stopping power is the mass stopping power.
str, optional) – An optional name for the layer.
