SPS Settings Copy

SPS Cycle & Super-cycle copy recommendations

Cycle level copy:

The cycle copy is presently operational.
For each cycle, select the source and the target cycle and perform the copy. Each copy may take ~10 minutes. The cycle copy first scans the settings and checks for inconsistencies and presents a popup with errors/warnings. Check the errors/warnings and apply the copy.
Exceptions/issues :
- The RBI.816 I/Iref settings may have to be regenerated/cleaned/trimmed manually after the copy because of the nature of the trims that are applied at the I/IREF level. It is recommended to trim at the I level (and not to touch the first and last points of the cycles). Unfortunately it is not possible to follow that rule strictly at the moment.

Beam process level copy:

By default the Settings Manager application of Anthony copies the ‘Correction’ part of the setting which is the CORRECT default.

Transfer lines (SPSInjection, CNGSTransfer, T2Transfer, T4Transfer, T6Transfer, LHCB1Transfer, LHCB2Transfer)

Copy of KNOBs is only needed for SPSInjection (all knobs should be zero on other transfers).
Copy all parameters at K-level (systems MOMENTUM, CORRECTORs (H and V), QUADRUPOLES must only be copied for CNGS & LHCBxTransfer)

. For CNGS a sign for a healthy and correct copy is that there is no interlock from the ROCS current surveillance (FEI).

Warning: CNGS & LHCB2 transfers:

At the moment we are running with either TI8 OR CNGS (due to access constraints). It is necessary to set to the minimum current the IREF function of the converter that powers both the CNGS & TI8 mains (RPPDT.BA4.RBI.81606/IREF) MANUALLY for the line that is not used!!

Extractions (EastExtraction, WestExtraction, NorthExtraction)

Copy all KNOBs for all systems.
Copy SEPTUM parameters at K-level.
Copying all other K-level parameters not needed, as all corrections should be 0.

SPSRing

Tune : Q-level (QH + QV) + Iref for all
Momentum : Iref, Imains
Qprime : KNOBs (QPRH + QPRV)
Correctors H + V : K-level
RF-Hadron200 : Bucket Area (mostly for LHC), Total Voltage
RF-Hadron800 : All parameters – only needed for LHC cycles
RF-LONG-FDBK : All parameters– only reeded for LHC cycles
Damper H+V : gains
Octupoles : K-level
RF_RADIAL: RADIAL_STEERING
Skew Quadrupuoles : K-level – usually at 0 but…

Other parameters are not needed for the moment !
