Accelerator Update

Friday September 3


    Level Run - 50% complete (During a level run an alignment crew checks all the magnets positions relative to survey monuments.)

    Shimming Dipoles - 20% complete

    Cold Lift Measurement - 100% complete (A cold lift measurement checks the position of the cryo magnet's coil.)

    Kaiser Coil Measurements - 100% complete (A Kaiser coil measurement checks to see if the cryo magnet's coil has twisted or shifted in any way.)

    BPM Upgrade - 80% of the tunnel work is complete (A BPM is a Beam Position Monitor.)

    Most of the Tevatron is at liquid nitrogen temperature. Tevatron sectors D4, E4, F2, and F3 are at room temperature.


    Low Energy LCW System Upgrade - 80% complete

    Power Amplifier Filament Power Supply LCW Hose Replacement - 20% complete
