Class Description


This device calculates the vertical and horizontal positions of the beam:

X = f (Ia,Ib,Ic Id,G,offsets,factors, geometry ...) Y = f (Ia,Ib,Ic Id,G,offsets,factors, geometry...)

where: Ia = current read on blade A Ib = current read on blade B Ic = current read on blade C Id = current read on blade D G = locum4 amplifier gain offsets & factors = attributes of the device geometry = property of the device

The calculation of beam position is the following: for square geometry { Qx = ((I0 + I3) - (I1 + I2))/Isum; Qz = ((I0 + I1) - (I3 + I2))/Isum; X = horizontalPositionFactor * Qx + horizontalPositionOffset; Z = verticalPositionFactor * Qz + verticalPositionOffset; } for cross geometry { Qx = (I1 - I0)/(I1 + I0); Qz = (I2 - I3)/(I2 + I3); X = horizontalPositionFactor * Qx + horizontalPositionOffset; Z = verticalPositionFactor * Qz + verticalPositionOffset; }

Properties:

Name Description
Locum4ProxyNameDevString Locum4 Proxy Name
GeometryDevShort you have to choose between 2 different modes, either insertion or bipolar mode. 2 possible values - 1 : insertion - 2 : bipolar
LowVoltageThresholdDevDouble if the input voltages of the ADC decrease this threshold, the corresponding average current attributes become ALARM ( ex : if |Vmes| < low_threshold)
HighVoltageThresholdDevDouble if the input voltages of the ADC exceed this threshold, the corresponding average current attributes become ALARM ( ex : if |Vmes|> threshold)
CurrentOffset0DevDouble current offset on channel 1
CurrentOffset1DevDouble current offset on channel 2
CurrentOffset2DevDouble current offset on channel 3
CurrentOffset3DevDouble current offset on channel 4
VoltageOffset0DevDouble voltage offset on channel 1
