3 phase installation commissioning approach
to disentangle potential problems build upon
previous experience
1. SPS extraction / TT40 (up to TED400353) 2.
Transfer line TI 8 (up to TED87765) 3. LHC
injection (up to TDI) ( temporary warm line up
to left of IP 8 !)
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)
early 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
late 2003
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
• 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.

Planning looks feasible, although not yet
achieved.
Progress constraints need to be closely
monitored. 2002 and even more 2003 are
decisive.
