calcRes

public static double calcRes(double wavelengthInAngstroms,
 double thetaDegrees)

Base definition of maximum resolution (from Bragg's Law with n=1)

Parameters:

wavelengthInAngstroms -

thetaDegrees - : incident angle to crystal plane (in degrees)

Returns:

calculated maximum resolution

calcRes

public static double calcRes(double wavelengthInAngstroms,
 double radius,
 double distance,
 double twoThetaDegrees)

Calculate maximum resolution given detector distance and extent (radius) that detector face extends No correction for position of beam centre on detector face at twoTheta=0 Here radius and distance parameters can be in any length unit, provided it is the same, millimetres is the convention

Parameters:

wavelengthInAngstroms -

radius - : deviation (mm) from twoTheta subtended by detector (centre to edge)

distance - : displacement (mm) from sample at centre of rotation to centre of detector at angle twoTheta

twoThetaDegrees - : angle subtended (degrees) between beam and detector position (sum of angle of incidence and diffraction)

Returns:

calculated maximum resolution
