Attributes:

Name Description
BrushScalar: DevDouble
AveragePressureScalar: DevDouble The mean of the pressures. This attribute is calculated from the pressures` values on the AllSRPressuresList property.
DipoleAveragePressureScalar: DevDouble The mean of the pressures in chambers next to dipoles. This attribute is calculated from the pressures` values on the DipolePressuresList property.
StraightSectionAveragePressureScalar: DevDouble The mean of the pressures in straight sections of the storage ring. This attribute is calculated from the pressures` values on the StraightSectionPressuresList property.
CurrentTimesLifetimeScalar: DevDouble
MaximumPressureScalar: DevDouble Maximum value among the pressures given on the AllSRPressuresList.
MaxPressureLocationScalar: DevString Location of maximum pressure occurence. Taken from descriptions in AllSRPressuresList.
AvgPressureByCurrentScalar: DevDouble Average pressure divided by beam current.
DipAvgPressureByCurrentScalar: DevDouble Average pressure from chambers next to dipoles divided by beam current.
StSecAvgPressureByCurrentScalar: DevDouble Average pressure from straight section chambers divided by beam current.

Commands:
