The FaradayCountAverages specifies the number of beam current measurements to average. In this case, the default is 1 for one beam current average. Note that the FaradayCountAverages value is also used for the Absorbed Current measurement (if indicated).
FaradayCupType=0
This option specifies the faraday cup type. It must be set to zero for automatic recording of the beam current. For manual entry of the beam current (some older SEM instruments), change this value to any non-zero value. In this case, the program will prompt the user for the beam current value. The default is zero for automatic beam current measurement.
FaradayWaitInTime=0.5
Specifies the amount of time in seconds to wait after inserting the faraday cup before starting the beam current acquisition. The allowable range is 0 to 100 seconds. The default value is 0.5 seconds.
FaradayWaitOutTime=0.5
Specifies the amount of time in seconds to wait after removing the faraday cup before starting the x-ray count acquisition. The allowable range is 0 to 100 seconds. The default value is 0.5 seconds.
AbsorbedCurrentPresent=0
This Boolean option specifies whether an absorbed current interface and associated hardware is present on the microprobe. If non-zero, the program will automatically acquire the absorbed current along with the faraday cup beam current.
AbsorbedCurrentType=0
This option specifies the absorbed current type. It is not used at this time.
DefaultBlankBeamFlag=1
This parameter is used to specify the default beam blank mode. Enter 0 for false or any non-zero value for true. If set to a non-zero value, the program will automatically leave the beam blanked after a stage motion command. If 0, the program will ask the user to confirm the beam unblank operation and then unblank the beam. The default is 1 to insert the faraday cup or blank the beam as the default.
MinimumFaradayCurrent=1.0
This parameter defines the threshold that the program uses to decide if the filament may have blown. The default threshold is 0.1 nA. The range of allowable values is 0.001 to 1000.
FaradayBeamCurrentSafeThreshold=500.0
This option sets the maximum safe threshold for the beam current so as to force the software to confirm with the user that it is safe to remove the faraday cup (or unblank) the beam. The default is 500 nA and the allowable range is 1 to 10,000 nA. Set this value lower to have the software confirm a manual faraday remove at lower currents.
FaradayStagePresent=0
This flag tells the software if a specimen (stage) mounted faraday cup is present. If this device is present a beam current reading will be made using the sample (specimen) current. Also the program will move the stage to the faraday stage position for each beam current measurement. Any non-zero value indicates that the faraday stage is present.
FaradayStagePositionsX=0.0
FaradayStagePositionsY=0.0
FaradayStagePositionsZ=0.0
FaradayStagePositionsW=0.0
These parameters allow the user to specify the default stage position (in x, y, z, (and w) ) for the specimen faraday measurement. These values can be updated in the program. These parameters must be in bounds for the x, y, z, (and w) positions.
