Update on BI devices integration in injection region
S. Gilardoni – BE/ABP
OP functional specs for BI injection devices
Functional specs for injection diag. available as EDMS document
PS PROTONS INJECTION DIAGNOSTICS - 1207510 Rev. 1.0
Date: 2012-05-08
Needs new specs because there will be no space in SS42 for beam
instrumentation devices due to the length of the future 2 GeV septum
Existing SS42 region
1.4 GeV SMH42
Future SS42 region before integration discussion
2 GeV SMH42
Decision after discussion on integration
-
The new semgrid should be placed at the beginning of MU42, replacing the
existing skew quadrupole
Only position sufficiently close the SMH42 and with enough beam
separation between circulating beam and injected one
The new BTV in front of the septum located in the BTP line will be placed
just before the beginning of the SMH42, in the new enlarged vacuum
chamber of MU41
The PUs in BTP will be displaced to have:
-
-
-
-
The second PU will be in BTP at pi/2 in phase advance wrt respect to
the first one
A fast BLM (plus a normal one) is already foreseen in the BI list for the new
installation also on top of MU42
-
-
The PU closest to the septum, i.e., at the beginning of the enlarged
common part of the new chamber of MU41. This to privilege the
aperture close to the septum.
