Insights into MINA Project H: Nonscaling Accelerator Beam Parameters and Simulation Studies

The MINA Project H focuses on an advanced model of a nonscaling accelerator, detailing critical beam parameters such as injection, extraction, kinetic energy, magnetic rigidity, and full emittance. Key performance metrics include a circumference of 18,109.7 m, maximum circulating current of 134 mA, and design objectives for future studies. Tracking simulations evaluate the lattice using ICOOL, with particular attention to tune variation versus momentum. The project aims to build magnets, develop diagnostics, and design components for ongoing phases, contributing to the development of innovative accelerator technologies.

  4. Tracking Simulations • Tracking studies of Sandro’s lattice with ICOOL

  5. Tracking Simulations • Tune variation versus momentum • Solid lines are matrix calculations, points are from tracking

  6. Magnets • Evaluated conventional, PM and Current-dominated (Panofsky) quads using Printed Circuit (PC) board coils.

  7. Magnets • Shown here are copper coils, however for the required field, PC boards would suffice

  8. Phase II Objectives • Design magnets; build octant (6 Periods) • Design, build, purchase diagnostics and gun • Perform experiment with octant and gun • Test ferrites and broadband materials (finemet etc) • Design cavity for Phase III • Design/cost Phase III Model
