Roberto Saban
Short Circuit Tests
Preparation for the first cool down
Enforce Safety
Quality Assurance
Tightening loose bolts
Resources

2. The tests of the power converters in short circuitPC
18kV for the dipole circuits
400V for the others
Water
UPS for all converters
above 4 kA
DCCT
Short Circuit
UA, UJ, RR
tunnel, UJ

3. The power converters & the associated systems
952 / 968 already installed

4. 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!

5. 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

6. High voltage tests of every circuit at warm
Positioning of the DC water cooled cables on the DFB
4.5K

7. High voltage tests of every circuit at warm
Safety measures & access restrictions

8. 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

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

450 Gev lower fields lower currents increased tolerance to temperature variations
Reduced commissioning times for some of the circuits
Reduced commissioning times for the calibration of instrumentation and tuning of temperature control loops

12. Resources

13. … 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
