Attributes:

Name Description
PositionScalar: DevULong Slide state as a DevULong (each bit representing one slide). Mainly used for testing, thus set to expert mode.
AttenuationScalar: DevDouble Beam attenuation in %. Since there is only a limited number of slide combinations and thus a limited number of possible attenuation values, you will almost never get precisely the attenuation you input here, but the value closest to the one you asked for.
UseOnlyScalar: DevString If you set this to any of the blade materials (e.g. Al), only blades with this material will be used when setting up the desired attenuation. Special value `any` sets the use of all blades. If you want to put in more than one material, separate names by `;` or `,`.
NextUpperScalar: DevDouble The next attenuation value higher than the one set which would result in a slide configuration change. Value will only be updated if attenuaton was changed via attribute Attenuation, but not if slides were moved with command Move or by writing true/false to the SlideXX attributes.
NextLowerScalar: DevDouble The next attenuation value lower than the one set which would result in a slide configuration change. Value will only be updated if attenuaton was changed via attribute Attenuation, but not if slides were moved with command Move or by writing true/false to the SlideXX attributes.
SlidersInSpectrum: DevBoolean Spectrum of the number of sliders in the system) telling which sliders are in the IN position. Only read.
SetInSpectrum: DevLong Spectrum of number of sliders in the system. for selecting the sliders that should be put in (they will be only move after executing the Move command). The read value indicates the sliders currently selected. 0 = not moved in 1 = moved in
SlidersOutSpectrum: DevBoolean Spectrum of thenumber of sliders in the system)telling which sliders are in the OUT position. Only read.

Commands:

Name Description
StateInput: DevVoid
Output: State
Device state
This command gets the device state (stored in its device_state data member) and returns it to the caller.
StatusInput: DevVoid
Output: ConstDevString
Device status
This command gets the device status (stored in its device_status data member) and returns it to the caller.
MoveInput: DevVoid
Output: DevVoid
Move to the in position the sliders set in the SetIn attribute.

Pipes:

Properties:

Name Description
NumberOfSlidesDevLong Number of slides in the absorber device. This should be the absolute number. If any slide does not contain absorption material, give its gauge as 0 in property gauges.
DynAttrListArray of DevString for internal use only
GaugesArray of DevDouble The gauge / thickness of the single slides, one per line in µ.
InvertIOLogicDevBoolean Depending on the assembly position (upside down or not) it might be necessary to invert the logic of true ( = slide in) and false ( = slide out). If this is set to true, the logic will be inverted.
XrayLibDeviceDevString Device name of xraylib server
EnergyAttributeDevString Attribute name where we can get the beam energy, e.g: petra/globals/keyword/Energy
MaterialsArray of DevString Atomic symbol of absorption material in slide, one per line.
SimulationModeDevBoolean
AbsorberDeviceDevString Device name of server controlling absorber hardware. The device has to provide: One void command `SetSliders`` taking a DevULong as argument; the bits of the argument represent the state of the sliders, 0 for out, 1 for in. One readable Spectrum attribute of DevBoolean. Each element represents one slide, true for in, false for out.
