RF Structure list RF structures are defined as physical entities allowing separate misalignments
number of sub-pieces (“ipiece”).

STRUC(i).RFPHASE
STRUC(i).ERRPHASE
STRUC(i).GRADIENT
STRUC(i).ERRGRAD
STRUC(i).DX(ipiece)
STRUC(i).DY(ipiece)
STRUC( i) .TYPE

STRUC(i).RFBPM-Y(2)
STRUC(i).RESOL
STRUC(i).FRF
Length of structure piece i in m.
Nominal phase of RF with respect to head of first bunch in
Radian.
Error of RF phase (Af,,)
in Radian.
Nominal gradient of acceleration in GeV/m.
Relative error of accelerating gradient (AE117.~J~~/EflP,L,~).
Horizontal misalignment of structure piece i in m.
Vertical misalignment of structure piece i in m.
INTEGER number indicating the structure type (e.g. SLC
has 3 different structure types, dimpling).
The modes in each structure can have frequency errors.
Only a limited number of such frequency errors is actually
generated and randomly assigned to structures. This INTEGER number gives the error type for each structure.
Horizontal up- and downstream beam position (wrt x=0) if
the RF structure i is used as an RF BPM.
Vertical up- and downstream beam position (wrt y=O) if the
RF structure i is used as an RF BPM.
Resolution of RF BPM.
RF frequency of particular structure.
Horizontal corrector list The horizontal correctors are described by the following information:
XCOR(i).LENGTH
XCOR(i).FIELD
XCOR(i).DFIELD
XCOR(i).TILT
XCOR(i).REF
Length of horizontal corrector i in m.
Integrated dipole field of horizontal corrector i in Tes1a.m.
Relative field error (ABIB).
Rotation about longitudinal axis in Radian.
Reference corrector strength.
Vertical corrector list The vertical correctors are described by the following information:

YCOR(i).LENGTH
YCOR(i).FIELD
YCOR(i).DFIELD
YCOR(i).TILT
YCOR(i).REF
Length of vertical corrector i in m.
Integrated dipole field of vertical corrector i in Tes1a.m.
Relative field error (ABIB).
