The Fermilab Main Injector dipole construction techniques and prototype magnet measurements

The Fermilab Main Injector Project will provide 120-150-GeV proton and antiproton beams for Fermilab Fixed Target Physics and Colliding Beams Physics use. A dipole magnet has been designed and prototypes constructed for the principal bending magnets of this new accelerator. The design considerations and fabrication techniques are described. Measurement results on prototypes are reported, emphasizing the field uniformity achieved in both body field and end field at excitation levels from injection at 0.1 T to full field of 1.7 T.<
