PowerPoint Presentation
The LT DipoleJuly 8th, 2014MotivationCombine expertise of LBNL & TAMU to overcome common obstacles and reach higher fields with regular milestonesModular approachLT1: 13T Nb3Sn open-aperture (9x5 cm2)LT2: 15T, LT1 + a racetrack of BSCCO-2212LT3: 19T, LT2 + a flared winding of BSCCO-2212Stress management and continuous support of reacted cable to avoid damage lossesMagnetics for LT1
Magnetics for LT2
Stress management structureMagnetics for LT3Before pancake windingAdd pic of just mandrel
Window for quench heaters and voltage taps
Mandrel heart
Magnetic cutout also serves as a slotCommon design allows part reuseThin-skin slots into placePancake and associated structure
Pre-structure for flare
These pieces provide supported form, and allow safe removal of flare873mm bending radius, 10 arc (same as HD3)Flared winding and structure
Pins for flare?Window for quench heaters and voltage tapsRemove mandrel heart and install spanner plates
Aperture now cleared in end piecesContinuous support of Nb3Sn mitigates assembly damageAssembling two halves
Common wall pushes out plates through thick-skinContinuous support of Nb3Sn mitigates assembly damageRemoval of spanner plates
Completed coil package
Bladder/key magnet assembly
Similar to HD2/HD3, yoke is keyed against shell, then coil package is inserted and keyed
