% X-ray tube
%-----------------------------------------------------------------------------------------------

% axial dimension (length, mm)
FocusH=12

% optical breadth (1/10 of the nominal) of the line focus (mm)
FocusW=0.04

% Goniometer radius (mm)

R=300


%-----------------------------------------------------------------------------------------------
% Divergence slit
%-----------------------------------------------------------------------------------------------

% Note: Bruker specifies the divergence slit in °, but BGMN requires the width of the
% slit in mm. Here we calculate the width from the divergence angle and the distance
% from the tube. For HSlitR enter any value shorter than the goniometer radius R,
% and HSlitW will calculate the slit width resulting in a divergence angle of "div" degrees.

% beam divergence (°)
div=0.6

% distance from sample (mm)
HSlitR=100

% fixed slit width (mm)
HSlitW=2*tan(div*pi/360)*(R-HSlitR)


%-----------------------------------------------------------------------------------------------
% Detector
%-----------------------------------------------------------------------------------------------

% total detector height (mm)
DetArrayW=14.4

% height of one strip (mm)
DetW=0.075

% total detector width (mm)
DetH=16


%-----------------------------------------------------------------------------------------------
% Sample holder
%-----------------------------------------------------------------------------------------------

% Note: The diameter was guessed!

% diameter of the sample holder (mm)
SamplD=25


%-----------------------------------------------------------------------------------------------
% Collimators (Soller slits)
%-----------------------------------------------------------------------------------------------

% Note: For some manufacturers we have to use half the opening angle given on the soller
% slits (Bruker), but for others (Panalytical) we have to use the full value. Here soller
% slits of 2.5° were used, which is 0.0436 radians. We use 0.0436 / 2 = 0.0218 rad.

% primary soller slit (radians)
PColl=0.0218

% secondary soller slit (radians)
SColl=0.0218


%-----------------------------------------------------------------------------------------------
% Anti-Scatter slit
%-----------------------------------------------------------------------------------------------

% opening in degrees
ass=9.96

% distance from sample (mm)
SSlitR=R-80

% slit width (mm)
SSlitW=2*tan(ass*pi/360)*(R-SSlitR)
