This algorithm uses Equations of state for Lead (111) to calculate the pressure of a given sample. The required inputs are the dSpacing (A) of the Lead (111) Bragg peak and the reference temperature (K).
Optionally, a further input of Target pressure (GPa) can be given, which will find the corresponding dSpacing for the pressure at the provided reference temperature.
Example:
from mantid.simpleapi import LeadPressureCalc
LeadPressureCalc(dSpacing=2.85, T=312, TargetPressure=0.0043)
The Equations of State and fit parameters used in this calculation can be found in:
