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
