Bent Laue Monochromators X-ray Optics
Project description
BLXO (Bent Laue X-ray Optics)
Installation
Option 1
pip install blxo
Option 2
Download the repository. Import the blxo
folder as a python package.
How to use it
-
Define a monochromator with your parameters.
Example:
from blxo import *
mono = mc.BentLaueMono(chi=np.radians(4.4671),theta=np.radians(8.99),nu=0.2,t=0.3,r=2000,p=22000) # Length unit is mm. Angle unit is radians.
-
Get the interested properties from the monochromator.
- Quasi-mono beam
qmb = mono.qmb # Quasi-mono beam width (mm) width = qmb['width'] # Quasi-mono beam footlength (mm) footlength = qmb['foot_length'] # Energy spread of the QMB in terms of angle (rad) ang_spread = qmb['angular_spread']
- Resolutions
# Energy resolution mono.energy_resolution # Energy resolution in terms of angle mono.angle_resolution
- Optimal focus-to-detector distance
mono.f2d_optimal
- Calculators for magic condition
from blxo import * # Expect the result to be zero when the magic condition is met. # Magic condition function in terms of angle mc_angle_misalignment = mc.magic_condition_angles(chi=np.radians(4.4671),theta=np.radians(8.99),nu=0.2,t=0.3,r=2000,p=22000) # `mc_angle_misalignment` is expected to be zero (or zero enough) when the magic condition is met. # Magic condition function in terms of foci mc_focus_misalignment = mc.magic_condition_foci(chi=np.radians(4.4671),theta=np.radians(8.99),nu=0.2,t=0.3,r=2000,p=22000) # Thickness (t) is not a factor in the calculation, but a called module requires it for some other functions. So just give it any number.
