  1. QD0 R&D Update presented by Brett Parker, BNL-SMD

  2. QD0 R&D Update All major parts and subassemblies needed for the QD0 R&D prototype and its Service Cryostat are now in hand. Assembly of the magnet & service cryostat will be completed before end of FY’13 (Sept’). We do not anticipate having sufficient funds remaining for full cold and vibration testing but we hope at least to test the Service Cryostat low temperature operation. “QD0 R&D Update,” Brett Parker, BNL-SMD

  5. Magnetic Stability Measurements R&D proceeds developing system with a 2500 turn pickup coil that is cantilevered into the magnet bore from a vibration isolation table. Our ultimate goal is to directly measure small magnetic field shifts due to magnet vibration. This technology will also be applied to the measurement of the SuperKEKG IR magnets. The above will be discussed at magnetic measurements workshop next week at BNL, IMMW 18. “QD0 R&D Update,” Brett Parker, BNL-SMD

  6. Consider Some New MDI Possibilities SuperKEKB Cancel Coil SuperKEKB Cancel Coil: Two Layer Sextupole Winding Pattern b3 a3 Normalized Shape Distribution Angle on Tube (Degrees) Z (mm) Z (mm) First Layer Wound Projected-Y (mm) 3D View “Twisted Coil” generates a3 from b3 Projected-Z (mm) Now have experience winding quite sophisticated superconducting coils (see SuperKEKB example). There are also new ideas for QD0 anti-solenoid. Can try to decrease cryostat transvers size while improving optics flexibility at low energy. There are also some new concepts to explore to improve anti-DID manufacture and integration. “QD0 R&D Update,” Brett Parker, BNL-SMD
