Scalar Attributes
Attribute name
Data Type
R/W Type
Expert
currentSlotName: The current slot name
DEV_STRING
READ
No
currentBehaviour: The current choosen behaviour.
DEV_STRING
READ
No
energy: The value of the energy of the monochromator
DEV_DOUBLE
READ_WRITE
No
lambda: The value of the wavelenght lambda.
DEV_DOUBLE
READ_WRITE
No
alpha: The alpha angle which represents the angle between the beam line and the grating.
DEV_DOUBLE
READ_WRITE
No
beta: The beta angle which represents the angle between the grating and the beam from the output of the grating.
DEV_DOUBLE
READ
No
mirrorDeviationAngle: The deviation angle of the mirror.
DEV_DOUBLE
READ_WRITE
No
currentResolutionCriterion: The current resolution criterion name (Fixed Resolution or Fixed Slits). If the Fixed Resolution criterion is choosen, the value of the attribute called resolution is used for the computing.
DEV_STRING
READ
No
currentVGDCriterion: The current VGD criterion name
DEV_STRING
READ
No
realConstraint: The value of the c constraint.
DEV_DOUBLE
READ_WRITE
No
currentConstraint: The current constraint value. In fact this is the last value used during during an energy write.
DEV_DOUBLE
READ
No
encoderConstraint: The value of the constraint according the position of the motors.
DEV_DOUBLE
READ
No
resolution: The current resolution
DEV_DOUBLE
READ
No
resolvingPower: The resolving power value (E/DeltaE)
DEV_DOUBLE
READ
No
selectedResolution: The selected resolution value. If we write a new value, the current resolution criterion is set to Fixed Resolution
DEV_DOUBLE
READ_WRITE
No
selectedResolvingPower: The selected resolving power value. If we write a new value, the current resolution criterion is set to Resolving Power Criterion
DEV_DOUBLE
READ_WRITE
No
selectedExitSlitAperture: Allow to select the exit slit aperture. When the value is changed, the gap value entered is send to the Slit Device and the Resolution criterion is set to Fixed Slits
DEV_DOUBLE
READ_WRITE
No
currentGratingSize: The current grating value in lines by millimeters.
DEV_DOUBLE
READ
No
currentGratingName: The name of the current grating of the current slot
DEV_STRING
READ
No
relativeGratingPosition: The relative position over the grating.
DEV_DOUBLE
READ_WRITE
No
currentGrooveDepth: The current groove depth of the grating
DEV_DOUBLE
READ
No
optimalHighFluxX: Give the optimal X VGD position for the current Energy for the High Flux criterion
DEV_DOUBLE
READ
No
optimalHighRejectionX: Give the optimal X VGD position for the current Energy for the High Harmonics Rejection
DEV_DOUBLE
READ
No
currentMirrorName: The current mirror name of the current slot.
DEV_STRING
READ
No
gratingPosition: The grating position value (for the VGD and the choice of the grating)
DEV_DOUBLE
READ_WRITE
Yes
exitSlitAperture: The exit slit aperture value
DEV_DOUBLE
READ_WRITE
Yes
