Preparation of the first cool down
 Many non conformities on cabling
 AC cables not crimped as per state of
the art
 DC cables with extensions
 Missing cable lengths
 Late or just in time (but too just)
installation of equipment
(electronics, cables, etc)
 Insufficient preparation of some
tests with respect to:
 Co-activities
 Access conditions
 Safety conditions
 It is the first one!
Roberto Saban
MAC 061208
High voltage tests of every circuit at warm
 Ensure both insulation to ground and among circuits
 Record reference values for leakage currents and
transfer functions
 All the instrumentation electronics is not yet ready,
therefore it was decided to carry-out the tests
without it




all quench protection equipment disconnected from
DFB
all current lead heater cables disconnected from DFB
cryogenic instrumentation cables disconnected from
DFB
DC cables clamped to leads with insulation in between
1.9K
4.5K

Preparation of the first cool down
 Ongoing individual system
tests
 Orbit correctors
 PC/cables polarity test
 PC tests
 HV tests
 Installation of BLMs ongoing
 Cryogenic operation
related activities
 Purging & filling of the helium
vessel & lines. Flushing, next
week

2007: the year of commissioning
cool down from 300 to 80 K
cool down from 80 to 4.5 K
cool down from 4.5 to 1.9 K
electrical quality assurance during
cool down
tuning of control loops
calibration of instrumentation
electrical quality assurance at cold
individual system tests at cold
powering tests
450 Gev
lower fields
lower currents
Reduced commissioning
times for some of the
circuits
Roberto Saban
increased tolerance to temperature
variations
Reduced commissioning times for the
calibration of instrumentation and tuning
of temperature control loops

… in summary
 Chasing all the completed warm
systems/components and organize
their commissioning
 Short circuit tests (power converters,
cabling, infrastructure) more than
half completed
 Preparing the cool down of the first
sector and … learning!
 Very worried for the availability of
resources beyond the first two sectors
