A5

Scattering Angle of All Analyzers

System Name: AnalyzerTheta

Type: Virtual

Brief Description

This device controls the "over all" angle of the 20 analyzers mounted in the kidney. When moved to a angle, all analyzers move to that angle.

Due to way the underlying analyzer's hardware is contructed, whenever this device is moved A6 is inheriently moved at the same time.

For compatibility reasons a move can still be issued to both A5 and A6 at the same time provided the destination for A6 is exactly twice the destination for A5. This is NO different from moving A5 by itself.

Whenever A5's angle is moved:

    All AnalyzerThetaNN devices are moved to the same position.
    
    The values of all EfNN devices are recalculated using the following formula:
    EfNN = 81.81 / ((2 * d-spacing * sin(AnalyzerThetaNN)) ^ 2)
    
    A6's value is recalculated from A5 using the following formula:
    A6 = 2 * A5 
    A6 = N/A if A5 is N/A.
    
    Ef's value is recalculated from A5 using the following formula:
    Ef = 81.81 / ((2 * d-spacing * sin(A5)) ^ 2) or
    Ef = N/A if A5 is N/A
