LHC Test Benches Activities: 2010-2011 Overview of Consolidation and Upgrades

This document outlines the activities and consolidation efforts of the LHC test benches from 2010 to 2011. Key highlights include successful qualification of dipoles for tunnel use, ongoing tests of shunted interconnections, and significant upgrades to the PS Booster's energy capacity. The report also details the validation tests conducted on electromagnetic systems, improvements made to measurement systems, and the establishment of a new database to manage data acquired during experiments. A focus on safety and efficiency remains paramount throughout all operations.

  2. Contents • 2010 Activities • Sparedipoles • LHC ShuntedInterconnection test • OSQAR Experiment and PS Booster upgrade • Test benches Consolidation • Miscellaneous • 2011 ForeseenActivities

  3. 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

  4. 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 shunt shunt

  5. 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

  6. 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.

  7. 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

  8. 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)
