Questions to be clarified
BPMs in BTP and PS injection region
Wires downstream PS injection region + electronics specification
Screen in BTP – disentangle emittance/dispersion contributions
BTM instrumentation
What remains to be updated in Madx files
Plan to have several meetings on these topics until everything clear - within the next 2 months

PS injection instrumentation
Presently SS42 includes 2 profile measurements
BTV upstream the 42 bumper
Wires in the SMH42 tank
Future SS42 will be fully covered by Septa tank (SMH42 and Bumper42)
Vacuum chamber Y upgraded for improved aperture
Installation this EYETS
Includes port for BTV slided into MU41
No BPM included
Wires will go to vacuum chamber of MU42
installation foreseen in LS2

8. BPM phase space coverage in BTP

BPM phase space coverage in BTP
Vertically well covered
Horizontally missing 90 deg upstream septum exit – coincides with kicker phase

9. Conclusion for BPMs in BTP

PS inj instrumentation, W. Bartmann
Conclusion for BPMs in BTP
Suggest to move BPM which is right downstream the last BTP quad as far downstream as possible
And add BPM at 90 deg H location wrt to septum exit – between QNO50 and 55; space available
The model of the 2 GeV stray field can be validated with the SS42 screen
The two BPMs with 90 deg phase advance in YASP should then allow for efficient injection steering and monitoring of trajectory variation – short and longterm
Wires downstream injection straight ensure clean steering onto machine orbit
