lhc consolidation
LHC Consolidation
  • SpareMagnets Tests
    • On Dec. 9th 2010, 22/44 dipoles tested and qualified as “OK for the tunnel”
    • 14 of themsince 1st of June (since the CRYO shutdown ) as 10 werescheduled
    • In Sm18 today : SSS367 (D1 bench) + 6 dipoles to betested
lhc shunted interconnection
LHC ShuntedInterconnection
  • Mandate of MSC-TF: Ensure the protection and the instrumentation for the Shunt validation test.
  • 2 Magnets (Q8 and Q9) on bench D2 from July 2010
  • Tests :
    • Thermal runaway : completedsuccessfully
    • Quench propagation : in progress
    • RRR measurements : PXI system validation (compared to NanoVoltmeter)
    • Current cycles : in progress

osqar experiment
OSQAR Experiment
  • TF section mandate : to train 2 dipoles to ultimatecurrent and ensure the protection
  • Photon regenerationexperimentperformedduring :
    • 4 days in Feb
    • 18 days in June and July
    • 8 days in Aug.

PS Booster upgrade

  • Original PS Booster energy: 800MeV, 0.6T, 2700A RMS
  • Final upgrade: 2GeV, 1.12T, 5515A RMS
  • Tests up to 9 kA have been completed for >5000 cycles
  • High currents and high ramp rates require powerful converters.
  • => Cluster A of the SM18 test benches is actually equipped with a 14kA/61V capacity power converter that fulfills the requirements
test benches consolidation
Test benches Consolidation
  • New acquisition systems
    • VME => PXI Bus
    • SUN replaced by PC (Windows and Linux)
    • Cluster E dedicated to validation tests
    • LF (1kHz max.) : 360 channels
    • HF (50kHz max.) : 160 channels
  • FGC2 Power convertors
    • All benches are nowequippedwith the same PC controls as the LHC.
  • Technical network
    • All protection and acquisition systems are been moved to TECNET.
miscellaneous
Miscellaneous
  • Magnetic measurements :
    • LHC current cycles characterization, with new ramp rates and maximum currents as required by the machine
    • Improvements of the FAME magnetic measurement system
  • Creation and management of the TF website
  • Visitors area and meeting room improvements
2011 activities
2011 Activities
  • Spares :
    • 22 Dipoles
    • 12 SSS
    • 3 Special SSS
    • SeparationDipoles and Inner Triplets : Priority to the D1L101
  • Q8-Q9 Shunted test :Decision in January for additionnal tests.
  • OSQAR :6 weekswith 2 magnets @1.9K
  • Magneticmeasurements : LHC characterization and FAME improvement (SSSs and dipoles)
  • Consolidation
    • Keithleys to PXI (RRR, Loss and Splicemeasurements) => February 2011
    • 7 HV racks to PXI => February 2011
    • New Acquisition system (Block4 + Clusters SM18)
    • Creation of a new database
  • CRYO Shutdown :Scheduled in May 2011 (6 weeks)
