Working Summary Schedule
TI 8 installation and commissioning / V. Mertens / LHC-TCC / 21. 9. 2001
3 phase installation + commissioning approach
to disentangle potential problems + build upon previous experience
1. SPS extraction / TT40 (up to TED400353)
early
2003
test equipment + tune extraction
test extraction performance / check for SPS errors (p-to-p reproducibility, drifts ?)
access system must be capable to handle varying conditions safely + efficiently
time sharing with bulk installation(s) to be agreed (+ interlocks to be set up)
2. Transfer line TI 8 (up to TED87765)
late
2003
debug full-size installation
investigate behaviour of line (time-dependent effects ?)
basic ingredients of definitive control system must be available (conc. on line !)
for beam tests: beam instrumentation must be available
[set up trajectory correction
 certainly not a one-shot action !
measure optical characteristics]
3. LHC injection (up to TDI) (+ temporary warm line up to left of IP 8 !)
as from
04/2004
set up injection equipment, as for nominal injection
learn to work with new software (establish seamless link with main ring BI,
prepare for future integration with LHC first turns (inj. oscillations, orbit FB, ...)
access + safety systems fully functional
interlocks primordial (at least at higher intensities)

Summary
•
An approach is proposed where installation and commissioning is split in 3 phases:
– SPS extraction / TT40
– TI 8
– injection elements + temporary warm line
•
•
•
•
Planning looks feasible,
although not yet achieved.
which should help to use subsequent test and beam times to their best,
i.e. to be best prepared for the sector test + injection milestone.
Many circumstances have to fit to translate this planning into reality
(extraction delivered, no CE delays, no crane breakdowns, …).
Main magnets incl. vacuum are already available, but many ingredients should arrive
just-in-time (MKI, MSI vacuum, transport system, …).
For certain elements surrogate solutions exist (e.g. MKI, if necessary).
Baseline planning is to have all injection elements (MKI, MSI, TDI/TCDD
+ associated vacuum + instrumentation) installed at their definitive
locations and the remainder to the triplet left of IP8 to be filled
temporarily by TI 2 and SPS material.
Progress + constraints need to be closely monitored.
2002 and even more 2003 are decisive.
